氧化锌/石墨烯异质结构的光电特性

In this paper, we present the result of a heterostructure fabricated on non-stoichiometric zinc oxide (ZnO1-x) film and graphene. ZnO1-x/graphene heterostructure were constructed by depositing ZnO1-x layer by magnetron sputtering and wet-method transferring graphene. Analaysed the results, we could find that ZnO1-x/graphene heterostructure is with some enhanced photo-electric properties. For instance, the absorbance of ZnO1-x/graphene in visible and near-infrared region is improved, and due to high conductivity of graphene, the current is increased significantly, both in dark and under irradiation of 700 nm. With calculation of absolute current gain, ZnO1-x/graphene has a higher current gain. Thus, ZnO1-x/graphene heterostructure would be widely applied in visible light to near-infrared detection in the future. n this paper……….. (10 Points, Times New Roman)
