The van der Waals interface between the graphene and MoS2 exhibits Schottky barrier. The application of gate voltage to the graphene layer enables us to modulate the Schottky barrier height; thus gives rise to the control of the current flow across the interface. By analyzing the temperature dependence of the conductance, the modulation of Schottky barrier height {\\Delta}{\\phi} has been directly determined. We observed significant MoS2 layer number dependence of {\\Delta}{\\phi}.
