Graphene is always used to construct two-dimensional (2D) van der Waals (vdW) heterostructures due to its excellent performance. Hydrogenated phosphorus carbides (HPC or PCH), as novel 2D carbon-based materials, are predicted to be potential for nanoelectronics and optoelectronics. Herein, we explore the electronic prop-erties of vdW heterostructure of graphene and hydrogenated phosphorus carbides under both strain and electric field by using first-principles calculations. The results demonstrate that the Schottky barrier height (SBH) and band gap of the heterostructures can be effectively mod...
