Crystal phases of charged interlayer excitons in van der Waals heterostructures

Abstract

Low-dimensional transition metal dichalcogenides are an ideal platform to investigate strongly correlated phenomena with excitons. Here, the authors theoretically demonstrate that bilayer heterostructures of these materials can be used to realize the strongly correlated many-particle states of charged interlayer excitons that can be controlled by the interlayer separation adjustment and can be tuned by both electro- and magneto-static external fields.
