Topological Insulators in Twisted Transition Metal Dichalcogenide Homobilayers
Topological Insulators in Twisted Transition Metal Dichalcogenide Homobilayers
We show that moir\'e bands of twisted homobilayers can be topologically nontrivial, and illustrate the tendency by studying valence band states in $\ifmmode\pm\else\textpm\fi{}K$ valleys of twisted bilayer transition metal dichalcogenides, in particular, bilayer ${\mathrm{MoTe}}_{2}$. Because of the large spin-orbit splitting at the monolayer valence band maxima, the low energy valence …
