Description:
Author(s): Lingjie Du, Tingxin Li, Wenkai Lou, Xingjun Wu, Xiaoxue Liu, Zhongdong Han, Chi Zhang, Gerard Sullivan, Amal Ikhlassi, Kai Chang, and Rui-Rui Du We report on a class of quantum spin Hall insulators (QSHIs) in strained-layer InAs / GaInSb quantum wells, in which the bulk gaps are enhanced up to fivefold as compared to the binary InAs / GaSb QSHI. Remarkably, with consequently increasing edge velocity, the edge conductance at zero and applied magn... [Phys. Rev. Lett. 119, 056803] Published Thu Aug 03, 2017
