摘要
We report a self-powered ultraviolet photodetector based on a single Sb-doped ZnO nanobelt bridging an Ohmic contact and a Schottky contact. The photoresponse sensitivity and the response time of the fabricated device are as high as 2200% and less than 100 ms, respectively. The performance of the device dramatically degrades as the Sb-doping concentration decreases in the ZnO nanobelt. The possible mechanisms have been proposed and discussed.
