High-buckled R3 stanene with topologically nontrivial energy gap
Ye-Heng Song, Zhi-Wen Wang, Zhen-Yu Jia +6
Stanene has been predicted to be a two-dimensional topological insulator (2DTI). Its low-buckled atomic geometry and the enhanced spin-orbit coupling are expected to cause a promin…

Aggregation of BiTe Monolayer on BiTe(111) Induced by Diffusion of Intercalated Atoms in van der Waals Gap
Zhi-Wen Wang, Wen-Kai Huang, Kai-Wen Zhang +3
We report a post-growth aging mechanism of BiTe(111) films with scanning tunneling microscopy in combination with density functional theory calculation. It is found that a…
