Quantum Spin Hall Effect and Topological Field Effect Transistor in Two-Dimensional Transition Metal Dichalcogenides

Xiaofeng Qian, Junwei Liu, Liang Fu +1

We report a new class of large-gap quantum spin Hall insulators in two-dimensional transition metal dichalcogenides, namely, MX${}_2$ with M=(Mo, W) and X=(S, Se, and Te), whose topo…
