Description:
Author(s): Chen Si, Junwei Liu, Yong Xu, Jian Wu, Bing-Lin Gu, and Wenhui Duan We propose two-dimensional (2D) topological insulators (TIs) in functionalized germanenes (GeX, X=H, F, Cl, Br, or I) using first-principles calculations. We find GeI is a 2D TI with a bulk gap of about 0.3 eV, while GeH, GeF, GeCl, and GeBr can be transformed into TIs with sizable gaps under achiev... [Phys. Rev.
