However, its inferior average ZT (ZTave) value makes PbS less competitive with its analogs PbTe and PbSe. To promote its thermoelectric performance, this study implements strategies of continuous Se alloying and Cu interstitial doping to synergistically tune thermal and electrical transport properties in n-type PbS. First, the lattice parameter of 5.93 Å in PbS is linearly expanded to 6.03 Å in PbS0.5Se0.5 with increasing Se alloying content. This expanded lattice in Se-alloyed PbS not only intensifies phonon scattering but also facilitates the formation of Cu interstitials. Based on the PbS0.6Se0.4 content with the minimal lattice thermal conductivity, Cu interstitials are introduced to improve the electron density, thus boosting the peak power factor, from 3.88 μW cm−1 K−2 in PbS0.6Se0.4 to 20.58 μW cm−1 K−2 in PbS0.6Se0.4−1%Cu. Meanwhile, the lattice thermal conductivity in PbS0.6Se0.4−x%Cu (x = 0–2) is further suppressed due to the strong strain field caused by Cu interstitials. Finally, with the lowered thermal conductivity and high electrical transport properties, a peak ZT ~1.1 and ZTave ~0.82 can be achieved in PbS0.6Se0.4 − 1%Cu at 300–773K, which outperforms previously reported n-type PbS."}],"intvolume":"         2","has_accepted_license":"1","file":[{"checksum":"7b5e8210ef1434feb173022c6dbbee0c","relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_name":"2023_InterdiscMaterials_Liu.pdf","file_id":"15015","date_updated":"2024-02-19T09:58:32Z","creator":"dernst","file_size":4675941,"date_created":"2024-02-19T09:58:32Z"}],"department":[{"_id":"MaIb"}],"month":"01","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","issue":"1","citation":{"ista":"Liu Z, Hong T, Xu L, Wang S, Gao X, Chang C, Ding X, Xiao Y, Zhao L. 2023.

However, the relatively high material processing cost limits their real applications. Silver selenide (Ag2Se) is one of the very few n-type thermoelectric (TE) materials for room-temperature applications. Herein, we report a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se, which can be extended to other metal chalcogenides. These materials reach TE figures of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide (Bi2S3) particles also prepared in an aqueous solution are incorporated into the Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt % of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering. The presence of Bi2S3 significantly improves the Seebeck coefficient and power factor while at the same time decreasing the thermal conductivity with no apparent drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT value (zTave) of 0.93 in the 300–390 K range is demonstrated.","lang":"eng"}],"publication_status":"epub_ahead","publication_identifier":{"eissn":["2637-6113"]},"oa_version":"Published Version","title":"Engineering of thermoelectric composites based on silver selenide in aqueous solution and ambient temperature","author":[{"first_name":"Bingfei","last_name":"Nan","full_name":"Nan, Bingfei"},{"last_name":"Li","full_name":"Li, Mengyao","first_name":"Mengyao"},{"last_name":"Zhang","full_name":"Zhang, Yu","first_name":"Yu"},{"full_name":"Xiao, Ke","last_name":"Xiao","first_name":"Ke"},{"last_name":"Lim","full_name":"Lim, Khak Ho","first_name":"Khak Ho"},{"orcid":"0000-0002-9515-4277","first_name":"Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng","last_name":"Chang"},{"first_name":"Xu","last_name":"Han","full_name":"Han, Xu"},{"last_name":"Zuo","full_name":"Zuo, Yong","first_name":"Yong"},{"full_name":"Li, Junshan","last_name":"Li","first_name":"Junshan"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"first_name":"Jordi","full_name":"Llorca, Jordi","last_name":"Llorca"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","last_name":"Ibáñez","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Cabot","full_name":"Cabot, Andreu","first_name":"Andreu"}],"scopus_import":"1","day":"05","article_type":"original","date_created":"2023-05-28T22:01:03Z","language":[{"iso":"eng"}],"oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Nan, Bingfei, et al. “Engineering of Thermoelectric Composites Based on Silver Selenide in Aqueous Solution and Ambient Temperature.” <i>ACS Applied Electronic Materials</i>, American Chemical Society, 2023, doi:<a href=\"https://doi.org/10.1021/acsaelm.3c00055\">10.1021/acsaelm.3c00055</a>.","apa":"Nan, B., Li, M., Zhang, Y., Xiao, K., Lim, K.

However, traditional doping inevitably deteriorates carrier mobility. Herein, we develop a strategy for fine tuning of defects to improve carrier mobility. To begin, n-type PbTe is created by compensating for the intrinsic Pb vacancy in bare PbTe. Excess Pb2+ reduces vacancy scattering, resulting in a high carrier mobility of ∼3400 cm2 V–1 s–1. Then, excess Ag is introduced to compensate for the remaining intrinsic Pb vacancies. We find that excess Ag exhibits a dynamic doping process with increasing temperatures, increasing both the carrier concentration and carrier mobility throughout a wide temperature range; specifically, an ultrahigh carrier mobility ∼7300 cm2 V–1 s–1 is obtained for Pb1.01Te + 0.002Ag at 300 K. Moreover, the dynamic doping-induced high carrier concentration suppresses the bipolar thermal conductivity at high temperatures. The final step is using iodine to optimize the carrier concentration to ∼1019 cm–3. Ultimately, a maximum ZT value of ∼1.5 and a large average ZTave value of ∼1.0 at 300–773 K are obtained for Pb1.01Te0.998I0.002 + 0.002Ag.

These interfaces between the SnTe matrix and the nanoprecipitates can enhance the average PF through the energy filtering effect. On the other hand, abundant and diverse nanoprecipitates can significantly diminish the lattice thermal conductivity (κlat) through enhanced phonon scattering. The synergistic effect of Bi2O3 resulted in a maximum ZT (ZTmax) value of 0.9 at SnTe-2% Bi2O3 and an average ZT (ZTave) value of 0.4 for SnTe-4% Bi2O3 from 300 K to 823 K.

Sn has been replaced with various lower group dopants to achieve successful p-type doping in SnSe with high ZT values. A known, facile, and powerful alternative way to introduce a hole carrier is to use a natural single Sn vacancy, VSn. Through transport and scanning tunneling microscopy studies, we discovered that VSn are dominant in high-quality (slow cooling rate) SnSe single crystals, while multiple vacancies, Vmulti, are dominant in low-quality (high cooling rate) single crystals. Surprisingly, both VSn and Vmulti help to increase the power factors of SnSe, whereas samples with dominant VSn have superior thermoelectric properties in SnSe single crystals. Additionally, the observation that Vmulti are good p-type sources observed in relatively low-quality single crystals is useful in thermoelectric applications because polycrystalline SnSe can be used due to its mechanical strength; this substance is usually fabricated at very high cooling speeds.","lang":"eng"}],"has_accepted_license":"1","publication_status":"published","publication_identifier":{"eissn":["1884-4057"],"issn":["1884-4049"]},"file_date_updated":"2022-05-23T06:47:57Z","title":"Unidentified major p-type source in SnSe: Multivacancies","oa_version":"Published Version","author":[{"full_name":"Nguyen, Van Quang","last_name":"Nguyen","first_name":"Van Quang"},{"first_name":"Thi Ly","last_name":"Trinh","full_name":"Trinh, Thi Ly"},{"orcid":"0000-0002-9515-4277","first_name":"Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng","last_name":"Chang"},{"first_name":"Li Dong","last_name":"Zhao","full_name":"Zhao, Li Dong"},{"last_name":"Nguyen","full_name":"Nguyen, Thi Huong","first_name":"Thi Huong"},{"first_name":"Van Thiet","last_name":"Duong","full_name":"Duong, Van Thiet"},{"first_name":"Anh Tuan","full_name":"Duong, Anh Tuan","last_name":"Duong"},{"first_name":"Jong Ho","full_name":"Park, Jong Ho","last_name":"Park"},{"last_name":"Park","full_name":"Park, Sudong","first_name":"Sudong"},{"last_name":"Kim","full_name":"Kim, Jungdae","first_name":"Jungdae"},{"full_name":"Cho, Sunglae","last_name":"Cho","first_name":"Sunglae"}],"day":"13","scopus_import":"1","article_type":"original","date_created":"2022-05-22T22:01:40Z","volume":14,"language":[{"iso":"eng"}],"oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"apa":"Nguyen, V.

One possibility is employing surfactant-free solution synthesis to produce nanopowders. We propose the strategy of functionalizing “naked” particles’ surface by inorganic molecules to control the nanostructure and, consequently, thermoelectric performance. In particular, we use bismuth thiolates to functionalize surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1) carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity reduction by small grain domains, grain boundaries and nanostructuration. Overall, the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed SnTe."}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"        61","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"has_accepted_license":"1","article_type":"original","date_created":"2022-07-31T22:01:48Z","volume":61,"title":"Surface functionalization of surfactant-free particles: A strategy to tailor the properties of nanocomposites for enhanced thermoelectric performance","oa_version":"Published Version","author":[{"last_name":"Chang","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng","orcid":"0000-0002-9515-4277","first_name":"Cheng"},{"first_name":"Yu","orcid":"0000-0001-7313-6740","last_name":"Liu","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Seungho","orcid":"0000-0002-6962-8598","last_name":"Lee","full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425"},{"last_name":"Spadaro","full_name":"Spadaro, Maria","first_name":"Maria"},{"first_name":"Kristopher M.","last_name":"Koskela","full_name":"Koskela, Kristopher M."},{"first_name":"Tobias","full_name":"Kleinhanns, Tobias","id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425","last_name":"Kleinhanns"},{"first_name":"Tommaso","orcid":"0000-0001-9732-3815","id":"D93824F4-D9BA-11E9-BB12-F207E6697425","full_name":"Costanzo, Tommaso","last_name":"Costanzo"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"first_name":"Richard L.","last_name":"Brutchey","full_name":"Brutchey, Richard L."},{"first_name":"Maria","orcid":"0000-0001-5013-2843","last_name":"Ibáñez","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"}],"day":"26","scopus_import":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","issue":"35","citation":{"chicago":"Chang, Cheng, Yu Liu, Seungho Lee, Maria Spadaro, Kristopher M.

Herein, we optimize the thermoelectric performance of polycrystalline SnSe produced by consolidating solution-processed and surface-engineered SnSe particles. In particular, the SnSe particles are coated with CdSe molecular complexes that crystallize during the sintering process, forming CdSe nanoparticles. The presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation step due to Zener pinning, yielding a material with a high density of grain boundaries. Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects at different length scales, which significantly reduce the thermal conductivity. The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit up to 2.2 at 786 K, which is among the highest reported for solution-processed SnSe."}],"intvolume":"        16","file_date_updated":"2022-03-02T16:17:29Z","publication_status":"published","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"scopus_import":"1","day":"25","author":[{"last_name":"Liu","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7313-6740","first_name":"Yu"},{"first_name":"Mariano","last_name":"Calcabrini","full_name":"Calcabrini, Mariano","id":"45D7531A-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Yu","full_name":"Yu, Yuan","first_name":"Yuan"},{"full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","orcid":"0000-0002-6962-8598","first_name":"Seungho"},{"first_name":"Cheng","orcid":"0000-0002-9515-4277","full_name":"Chang, Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang"},{"last_name":"David","full_name":"David, Jérémy","first_name":"Jérémy"},{"first_name":"Tanmoy","full_name":"Ghosh, Tanmoy","id":"a5fc9bc3-feff-11ea-93fe-e8015a3c7e9d","last_name":"Ghosh"},{"first_name":"Maria Chiara","last_name":"Spadaro","full_name":"Spadaro, Maria Chiara"},{"full_name":"Xie, Chenyang","last_name":"Xie","first_name":"Chenyang"},{"full_name":"Cojocaru-Mirédin, Oana","last_name":"Cojocaru-Mirédin","first_name":"Oana"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","first_name":"Maria","orcid":"0000-0001-5013-2843"}],"title":"Defect engineering in solution-processed polycrystalline SnSe leads to high thermoelectric performance","oa_version":"Published Version","volume":16,"date_created":"2021-09-24T07:55:12Z","article_type":"original","oa":1,"language":[{"iso":"eng"}],"citation":{"apa":"Liu, Y., Calcabrini, M., Yu, Y., Lee, S., Chang, C., David, J., … Ibáñez, M.

Subsequently, nanoparticles are annealed in a reducing atmosphere to remove surface oxide, and consolidated into dense polycrystalline materials by means of spark plasma sintering. By characterizing the transport properties of the sintered material, we observe the annealing step and the incorporation of Cu to play a key role in promoting the thermoelectric performance of PbS. The presence of Cu allows improving the electrical conductivity by increasing the charge carrier concentration and simultaneously maintaining a large charge carrier mobility, which overall translates into record power factors at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room temperature and ZT = 1.22 at 773 K. Besides, a record average ZTave = 0.76 is demonstrated in the temperature range 320–773 K for n-type Pb0.955Cu0.045S."}],"intvolume":"       433","date_created":"2021-12-19T23:01:33Z","article_type":"original","volume":433,"oa_version":"Submitted Version","title":"Room temperature aqueous-based synthesis of copper-doped lead sulfide nanoparticles for thermoelectric application","scopus_import":"1","day":"01","author":[{"first_name":"Mengyao","last_name":"Li","full_name":"Li, Mengyao"},{"last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","full_name":"Liu, Yu","first_name":"Yu","orcid":"0000-0001-7313-6740"},{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"first_name":"Cheng","orcid":"0000-0002-9515-4277","full_name":"Chang, Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang"},{"last_name":"Zhang","full_name":"Zhang, Ting","first_name":"Ting"},{"first_name":"Dawei","last_name":"Yang","full_name":"Yang, Dawei"},{"first_name":"Ke","last_name":"Xiao","full_name":"Xiao, Ke"},{"first_name":"Jordi","last_name":"Arbiol","full_name":"Arbiol, Jordi"},{"full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","first_name":"Maria"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}]},{"type":"journal_article","date_updated":"2024-01-22T08:13:43Z","_id":"12155","publisher":"Royal Society of Chemistry","doi":"10.1039/d2ee02408j","article_processing_charge":"No","quality_controlled":"1","page":"4527-4541","keyword":["Pollution","Nuclear Energy and Engineering","Renewable Energy","Sustainability and the Environment","Environmental Chemistry"],"external_id":{"isi":["000863642400001"]},"related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1039/d3ee90067c"}]},"isi":1,"year":"2022","acknowledgement":"We acknowledge support from the National Key Research and Development Program of China (2018YFA0702100), the National Natural Science Foundation of China (51571007, 51772012, 52002011 and 52002042), the Basic Science Center Project of National Natural Science Foundation of China (51788104), Beijing Natural Science Foundation (JQ18004), 111 Project (B17002), and the National Science Fund for Distinguished Young Scholars (51925101).","date_published":"2022-11-01T00:00:00Z","publication":"Energy & Environmental Science","status":"public","article_type":"original","date_created":"2023-01-12T12:08:41Z","volume":15,"title":"Solid-state cooling: Thermoelectrics","oa_version":"None","author":[{"full_name":"Qin, Yongxin","last_name":"Qin","first_name":"Yongxin"},{"last_name":"Qin","full_name":"Qin, Bingchao","first_name":"Bingchao"},{"first_name":"Dongyang","full_name":"Wang, Dongyang","last_name":"Wang"},{"full_name":"Chang, Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang","first_name":"Cheng","orcid":"0000-0002-9515-4277"},{"last_name":"Zhao","full_name":"Zhao, Li-Dong","first_name":"Li-Dong"}],"scopus_import":"1","day":"01","publication_status":"published","publication_identifier":{"eissn":["1754-5706"],"issn":["1754-5692"]},"intvolume":"        15","abstract":[{"lang":"eng","text":"The growing demand of thermal management in various fields such as miniaturized 5G chips has motivated researchers to develop new and high-performance solid-state refrigeration technologies, typically including multicaloric and thermoelectric (TE) cooling.

has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications. In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief background introduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials (PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap engineering and vacancy compensation. We found that PbTe can significantly reduce the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain boundary could also reduce the intergrain energy barrier which largely enhances the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe.

SnTe is a promising candidate due to its high charge transport performance. Here, we prepared SnTe nanocomposites by employing an aqueous method to synthetize SnTe nanoparticles (NP), followed by a unique surface treatment prior NP consolidation. This synthetic approach allowed optimizing the charge and phonon transport synergistically. The novelty of this strategy was the use of a soluble PbS molecular complex prepared using a thiol-amine solvent mixture that upon blending is adsorbed on the SnTe NP surface. Upon consolidation with spark plasma sintering, SnTe-PbS nanocomposite is formed. The presence of PbS complexes significantly compensates for the Sn vacancy and increases the average grain size of the nanocomposite, thus improving the carrier mobility. Moreover, lattice thermal conductivity is also reduced by the Pb and S-induced mass and strain fluctuation. As a result, an enhanced ZT of ca. 0.8 is reached at 873 K. Our finding provides a novel strategy to conduct rational surface treatment on NP-based thermoelectrics.","lang":"eng"}],"acknowledged_ssus":[{"_id":"EM-Fac"}],"publication_status":"published","publication_identifier":{"eissn":["1996-1944"]},"file_date_updated":"2021-10-14T11:56:39Z","author":[{"id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng","last_name":"Chang","orcid":"0000-0002-9515-4277","first_name":"Cheng"},{"last_name":"Ibáñez","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","first_name":"Maria","orcid":"0000-0001-5013-2843"}],"day":"19","scopus_import":"1","oa_version":"Published Version","title":"Enhanced thermoelectric performance by surface engineering in SnTe-PbS nanocomposites","volume":14,"article_type":"original","date_created":"2021-10-03T22:01:23Z","project":[{"_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications","grant_number":"M02889"}],"publication":"Materials","status":"public","pmid":1,"date_published":"2021-09-19T00:00:00Z","acknowledgement":"The authors thank the EMF facility in IST Austria for providing SEM and EDX measurements.\r\n","isi":1,"year":"2021","external_id":{"isi":["000700689400001"],"pmid":["34576640"]},"ddc":["540"],"quality_controlled":"1","doi":"10.3390/ma14185416","article_processing_charge":"Yes","publisher":"MDPI","date_updated":"2023-08-14T08:00:01Z","_id":"10073","type":"journal_article"},{"file_date_updated":"2022-02-03T13:16:14Z","publication_status":"published","publication_identifier":{"eissn":["1521-4095"],"issn":["0935-9648"]},"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"abstract":[{"lang":"eng","text":"Solution synthesis of particles emerged as an alternative to prepare thermoelectric materials with less demanding processing conditions than conventional solid-state synthetic methods. However, solution synthesis generally involves the presence of additional molecules or ions belonging to the precursors or added to enable solubility and/or regulate nucleation and growth. These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions. These results highlight the importance of considering all the possible unintentional impurities to establish proper structure-property relationships and control material properties in solution-processed thermoelectric materials."}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"        33","has_accepted_license":"1","date_created":"2021-10-11T20:07:24Z","article_type":"original","volume":33,"oa_version":"Published Version","title":"The importance of surface adsorbates in solution‐processed thermoelectric materials: The case of SnSe","day":"29","scopus_import":"1","author":[{"last_name":"Liu","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu","orcid":"0000-0001-7313-6740"},{"first_name":"Mariano","orcid":"0000-0003-4566-5877","last_name":"Calcabrini","full_name":"Calcabrini, Mariano","id":"45D7531A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Yu, Yuan","last_name":"Yu","first_name":"Yuan"},{"last_name":"Genç","full_name":"Genç, Aziz","first_name":"Aziz"},{"full_name":"Chang, Cheng","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang","orcid":"0000-0002-9515-4277","first_name":"Cheng"},{"last_name":"Costanzo","id":"D93824F4-D9BA-11E9-BB12-F207E6697425","full_name":"Costanzo, Tommaso","first_name":"Tommaso","orcid":"0000-0001-9732-3815"},{"first_name":"Tobias","full_name":"Kleinhanns, Tobias","id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425","last_name":"Kleinhanns"},{"first_name":"Seungho","orcid":"0000-0002-6962-8598","id":"BB243B88-D767-11E9-B658-BC13E6697425","full_name":"Lee, Seungho","last_name":"Lee"},{"first_name":"Jordi","full_name":"Llorca, Jordi","last_name":"Llorca"},{"first_name":"Oana","full_name":"Cojocaru‐Mirédin, Oana","last_name":"Cojocaru‐Mirédin"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez","first_name":"Maria","orcid":"0000-0001-5013-2843"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Liu Y, Calcabrini M, Yu Y, Genç A, Chang C, Costanzo T, Kleinhanns T, Lee S, Llorca J, Cojocaru‐Mirédin O, Ibáñez M. 2021.
