摘要：
Electrochemically reduced TiO2 nanorod arrays (R-NRAs) have been used for the first time to construct a self-powered, visible light blind ultraviolet (UV) photodetector. The fabricated R-NRAs device demonstrated superior photodetector performance with high photon-to-current efficiency of up to 22.5% at an applied bias of 0 V. The enhancement is attributed to a disordered surface layer which greatly improves the charge separation and transfer efficiency at the electrode/electrolyte interface.
