text: There is a need for the development of lead-free thermoelectric materials
for medium-/high-temperature applications. Here, we report a thiol-free tin telluride
(SnTe) precursor that can be thermally decomposed to produce SnTe crystals with
sizes ranging from tens to several hundreds of nanometers. We further engineer
SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing
the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles.
The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase
effectively improves the electrical conductivity of SnTe while simultaneously
reducing the lattice thermal conductivity without compromising the Seebeck coefficient.
Overall, power factors up to 3.63 mW m–1 K–2 and thermoelectric figures of merit
up to 1.04 are obtained at 823 K, which represent a 167% enhancement compared
with pristine SnTe.

text: The direct, solid state, and reversible conversion between heat and electricity
using thermoelectric devices finds numerous potential uses, especially around
room temperature. 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.

text: High carrier mobility is critical to improving thermoelectric performance
over a broad temperature range. 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 findings
demonstrate that fine tuning of defects with <0.5% impurities can remarkably enhance
carrier mobility and improve thermoelectric performance.

text: SnTe is a promising Pb-free thermoelectric (TE) material with high electrical
conductivity. We discovered the synergistic effect of Bi2O3 on enhancing the average
power factor (PF) and overall ZT value of the SnTe-based thermoelectric material.
The introduction of Bi2O3 forms plenty of SnO2, Bi2O3, and Bi-rich nanoprecipitates.
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. The work provides an excellent
reference to develop non-toxic high-performance TE materials.

text: Thermoelectric materials allow for direct conversion between heat and electricity,
offering the potential for power generation. The average dimensionless figure
of merit ZTave determines device efficiency. N-type tin selenide crystals exhibit
outstanding three-dimensional charge and two-dimensional phonon transport along
the out-of-plane direction, contributing to a high maximum figure of merit Zmax
of ~3.6 × 10−3 per kelvin but a moderate ZTave of ~1.1. We found an attractive
high Zmax of ~4.1 × 10−3 per kelvin at 748 kelvin and a ZTave of ~1.7 at 300 to
773 kelvin in chlorine-doped and lead-alloyed tin selenide crystals by phonon-electron
decoupling. The chlorine-induced low deformation potential improved the carrier
mobility. The lead-induced mass and strain fluctuations reduced the lattice thermal
conductivity. Phonon-electron decoupling plays a critical role to achieve high-performance
thermoelectrics.

text: 'The broad implementation of thermoelectricity requires high-performance and
low-cost materials. 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.'

text: SnSe has emerged as one of the most promising materials for thermoelectric
energy conversion due to its extraordinary performance in its single-crystal form
and its low-cost constituent elements. However, to achieve an economic impact,
the polycrystalline counterpart needs to replicate the performance of the single
crystal. 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.

text: A versatile, scalable, room temperature and surfactant-free route for the
synthesis of metal chalcogenide nanoparticles in aqueous solution is detailed
here for the production of PbS and Cu-doped PbS nanoparticles. 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.

text: Thermoelectric materials enable the direct conversion between heat and electricity.
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.

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.
