Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides (open access)

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides

This article shows that a bilayer of 2H-MoSâ‚‚ is an orbital Hall insulator that exhibits a sizeable orbital Hall effect in the absence of both spin and valley Hall effects. The results are based on density functional theory and low-energy effective model calculations and strongly suggest that bilayers of TMDs are highly suitable platforms for direct observation of the orbital Hall insulating phase in two-dimensional materials.
