In this work, a planar structured GaN/CuI heterojunction ultraviolet photodetector (UVPD) with a self-powered manner was constructed by the spin-coating method. Both UVA and UVC waveband lights were precisely detected by this designed GaN/CuI PD. Irradiated upon 365 nm UVA light, our PD device perfo...
