An inhomogeneous dephasing time T2* ∼ 0.18 μs exceeds corresponding measurements in III-V semiconductors by more than an order of magnitude, as expected for predominately nuclear-spin-free materials. Dephasing is observed to be exponential in time, indicating the presence of a broadband noise source, rather than Gaussian, previously seen in systems with nuclear-spin-dominated dephasing."}],"date_created":"2018-12-11T11:44:37Z","intvolume":"        14","publisher":"American Chemical Society","author":[{"id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","first_name":"Andrew P","last_name":"Higginbotham","orcid":"0000-0003-2607-2363","full_name":"Higginbotham, Andrew P"},{"first_name":"Thorvald","last_name":"Larsen","full_name":"Larsen, Thorvald"},{"first_name":"Jun","last_name":"Yao","full_name":"Yao, Jun"},{"last_name":"Yan","full_name":"Yan, Hao","first_name":"Hao"},{"full_name":"Lieber, Charles","last_name":"Lieber","first_name":"Charles"},{"last_name":"Marcus","full_name":"Marcus, Charles","first_name":"Charles"},{"first_name":"Ferdinand","last_name":"Kuemmeth","full_name":"Kuemmeth, Ferdinand"}],"external_id":{"arxiv":["1403.2093"]},"title":"Hole spin coherence in a Ge/Si heterostructure nanowire","doi":"10.1021/nl501242b","oa_version":"Preprint","issue":"6","status":"public","acknowledgement":"Funding from the Department of Energy, Office of Science & SCGF, the EC FP7-ICT project SiSPIN no. 323841, and the Danish National Research Foundation is acknowledged.","year":"2014","publication":"Nano Letters","type":"journal_article","volume":14,"citation":{"chicago":"Higginbotham, Andrew P, Thorvald Larsen, Jun Yao, Hao Yan, Charles Lieber, Charles Marcus, and Ferdinand Kuemmeth. “Hole Spin Coherence in a Ge/Si Heterostructure Nanowire.” <i>Nano Letters</i>.
