Atomic Distributions in Topological Insulator Bi${}_2$Se${}_{3-x}$Te${}_x$

Kaixin Huang, Haotian Zheng, Weidong Luo

Bi${}_2$Se${}_3$ is a topological insulator and it is often doped with Te to compensate the $n$-type carriers due to Se vacancies. Different doping patterns of Te would influence the t…
