Tuning Interfacial Excitonic Binding in Twisted Two-Dimensional MoS2 Bilayers

Two-dimensional (2D) layered molybdenum disulfide (MoS2) has attracted much attention due to its outstanding intrinsic properties and diverse applications. Defects and heterostructures usually play an important role in tailoring the various properties of MoS2 based 2D materials. And strong excitonic effect due to the quantum confinement in 2D MoS2 may be responsible for large variation of electric and optical properties...
