Abstract

Graphene quantum dots (GQDs) interacting with molybdenum disulfide (MoS₂) monolayers induce an effective photoexcited charge transfer at the interface. Both the photoluminescence (PL) and valley polarization of this GQDs/MoS₂ heterostructure can be modulated under various doping charge densities. The photon-exciton interaction is used to explain and calculate the heterostructure PL control, and is further applied to the valley-polarization tuning.
