Realistic tight-binding model for monolayer transition metal dichalcogenides in 1T' structure

Mengli Hu, Guofu Ma, Chun Yu Wan +1

Monolayer transition metal dichalcogenides $M{X}_2$ ($M$ = Mo,W and $X$ = Te, Se, S) in 1T' structure were predicted to be quantum spin Hall insulators based on first-principles calc…
