Abstract

With the development of the high-speed information era, dual-band response devices have attracted much attention. In this paper, a Cu₂O/TiO₂ heterojunction photodetector (PD) prepared by hydrothermal method and electrochemical deposition method is reported, which is simple, low-cost, non-toxic and pollution-free, and has a dual-band spectral response in the ultraviolet and visible ranges, and the responsivities of 0.029 and 0.078 A W^-1 are obtained, respectively. This study provides a reference for potential applications of high-performance dual-band PDs.
