The electrical characteristics of the graphene/Al-ZnO schottky contact with the temperature of 180 K-300 K have been discussed in detail. Based on the TE model, the barrier height increased and the ideal factor decreased with the increasing of temperature from 180 K to 300 K, which can be interpreted by the lateral inhomogeneities of schottky barrier height. Combined with the single gauss distribution function of barrier height, the lateral inhomogeneities distribution of barrier height at the interface was confirmed. By DLTS measurement, one electron trap centers were observed at the interface.
