Novel exciton optical physics in moiré superlattice structure of twisted stacked two-dimensional semiconductors

抄録

Two-dimensional materials, including graphene and monolayer transition metal dichalcogenides and their van der Waals heterostructures, have attracted tremendous attention because of the intriguing electronic and optical properties of extreme low dimensionality. The moiré superlattice in twisted van der Waals heterostructure drastically endows novel optical properties and functionality originating from twist angle-dependent electronic properties, offering applications for quantum information and quantum optics. This article introduces the novel optical physics of the moiré superlattice arising from moiré exciton states in a twisted WSe₂/MoSe₂ heterobilayer.
