摘要:In this study, we demonstrate a relatively independent UV photodetector which is composed of one layer of Au/Ag/Pt metal nanoparticles sandwiched between two layers of n-type TiO2 semiconductor nanorods. Different from most reported Schottky junction based UV photodetectors, it can be driven only by two opposite Schottky junction in the sandwich structure, but no need for any external power supply except UV light when it works. Moreover, it displays high responsivity and fast response speed at the same time, giving a bright prospect for self-powered UV photodetectors. (C) 2017 Elsevier B.V. All rights reserved.
