Efficient charge transfer between ZnO quantum dots (QDs) and graphene is demonstrated by decorating ZnO QDs on top of graphene, with the assistance of oxygen molecules from the air. The electrical response of the device to UV light is greatly enhanced, and a photoconductive gain of up to 10(7) can be obtained.
通过在石墨烯上修饰 ZnO 量子点(QD),在空气中氧气分子的辅助下,实现了 ZnO QD 和石墨烯之间的高效电荷转移。该器件对紫外光的电响应得到了极大的增强,可获得高达 10(7)的光电导增益。
