•The Schottky contact formed between graphene and SiCP4 is studied.•The barrier height and contact type can be tuned by changing the interlayer distance.•The charge transfer theory can be used to explain the change of Schottky barrier.•The Schottky barrier can be controlled by applying a vertical el...
