Self-Powered UV Photodetector Based on Zr-Doped TiO2 Nanorod Arrays with Improved Photoelectrochemical Performance
This study demonstrates that Zr doping in TiO2 nanorod arrays significantly enhances carrier separation and interfacial charge-transfer kinetics, enabling a high-performance, self-powered UV photodetector with a superior on/off ratio and specific detectivity under zero bias.
