Abstract
We developed theory of the magnetic edge states in a half-plane of transition metal dichalcogenide (TMDC) monolayer. The main qualitative feature of such system that distinguishes it from an unbounded plane is "tau-splitting", that is lifting of the valley degeneracy in an energy spectrum. Interband optical transitions are characterized by the violation of the selection rules established for the same transitions in an unbounded monolayer. |
