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."}],"status":"public","date_updated":"2021-01-12T08:22:24Z","intvolume":"        14","main_file_link":[{"url":"https://arxiv.org/abs/1403.2093","open_access":"1"}],"extern":"1","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.","publication_status":"published","oa":1,"publisher":"American Chemical Society","citation":{"mla":"Higginbotham, Andrew P., et al. “Hole Spin Coherence in a Ge/Si Heterostructure Nanowire.” <i>Nano Letters</i>, vol. 14, no. 6, American Chemical Society, 2014, pp. 3582–86, doi:<a href=\"https://doi.org/10.1021/nl501242b\">10.1021/nl501242b</a>.","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>.
