摘要	We have demonstrated a self-powered solar-blind ultraviolet (UV) photodetector based on the Au/ZnMgO/ZnO:Al vertical structure. The comb-shaped Au was selected as the Schottky electrode due to its high transmittance (more than 60%) in the wavelength region from 200 nm to 300 nm. At 0 V bias, the detector showed a responsivity of 55 mA/W under 265 nm light illumination with the intensity of 80 nW/cm(2), which is larger than that of any other previously reported ZnO-based self-powered UV photodetectors. And a fast response speed can be also clearly observed with 10%-90% rise and 90%-10% decay times of 20 mu s and 300 mu s, respectively. The excellent self-powered solar-blind UV detection of our Au/ZnMgO/ZnO:Al device should be associated with the high external quantum efficiency, especially for the weak signal detection. Our findings offered new chances in high-performance self-powered photodetectors fabrication. (C) 2019 Elsevier B.V. All rights reserved.
