--- _id: '97' abstract: - lang: eng text: The distribution of Coulomb blockade peak heights as a function of magnetic field is investigated experimentally in a Ge-Si nanowire quantum dot. Strong spin-orbit coupling in this hole-gas system leads to antilocalization of Coulomb blockade peaks, consistent with theory. In particular, the peak height distribution has its maximum away from zero at zero magnetic field, with an average that decreases with increasing field. Magnetoconductance in the open-wire regime places a bound on the spin-orbit length (lso < 20 nm), consistent with values extracted in the Coulomb blockade regime (lso < 25 nm). acknowledgement: Research supported by the Danish National Research Foundation, the Office of Science at the U.S. Department of Energy, the National Science Foundation (PHY-1104528), and the Defense Advanced Research Projects Agency through the QuEST Program. article_number: '216806' author: - first_name: Andrew P full_name: Higginbotham, Andrew P id: 4AD6785A-F248-11E8-B48F-1D18A9856A87 last_name: Higginbotham orcid: 0000-0003-2607-2363 - first_name: Ferdinand full_name: Kuemmeth, Ferdinand last_name: Kuemmeth - first_name: Thorvald full_name: Larsen, Thorvald last_name: Larsen - first_name: Mattias full_name: Fitzpatrick, Mattias last_name: Fitzpatrick - first_name: Jun full_name: Yao, Jun last_name: Yao - first_name: Hao full_name: Yan, Hao last_name: Yan - first_name: Charles full_name: Lieber, Charles last_name: Lieber - first_name: Charles full_name: Marcus, Charles last_name: Marcus citation: ama: Higginbotham AP, Kuemmeth F, Larsen T, et al.
