Nanocrystalline graphene–MoS 2 lateral interfaces reveal distinct current‐rectified characteristics, similar to a p–n diode, that are seldom observed for the monolayer graphene–MoS 2 vertical interface. It is found that the lateral interfaces can increase the Schottky barrier between the graphene and the MoS 2 because the metallic MoS 2 edges cause charge reordering and a potential shift in the graphene.
