Query: Modulation of Schottky barrier height in graphene/MoS2/metal vertical
  heterostructure with large current ON-OFF ratio   Detail transport properties of graphene/MoS2/metal vertical heterostructure
have been investigated. 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}. Moreover, we demonstrate that
the device which shows larger {\Delta}{\phi} exhibits larger current
modulation; this is consistent with the fact that the transport of these
devices is dominated by graphene/MoS2 Schottky barrier.
