Strong interlayer interactions in bilayer and trilayer moire superlattices.

ABSTRACT: Moiré superlattices constructed from transition metal dichalcogenides have demonstrated a series of emergent phenomena, including moiré excitons, flat bands, and correlated insulating states. All of these phenomena depend crucially on the presence of strong moiré potentials, yet the properties of these moiré potentials, and the mechanisms by which they can be generated, remain largely open questions. Here, we use angle-resolved photoemission spectroscopy with submicron spatial resolution to investigate an aligned WS₂/WSe₂ moiré superlattice and graphene/WS₂/WSe₂ trilayer heterostructure. Our experiments reveal that the hybridization between moiré bands in WS₂/WSe₂ exhibits an unusually large momentum dependence, with the spl
