White-light-controlled resistive switching chearacteristics of TiO₂/Cu₂O composite nanorods array

TiO₂/Cu₂O composite nanorods array were grown on fluorine-doped tin oxide (FTO) substrate by hydrothermal process, and white-light-controlled resistive switching characteristics of Ag/[TiO₂/Cu₂O]/FTO structure were further investigated. The current-voltage characteristics of the composite nanorods array represent a good rectifying property and bipolar resistive switching behavior. Specially, the resistive switching behavior can be regulated by white-light illuminating at room temperature. This study is helpful for exploring the memory materials and their applications in nonvolatile light-controlled memory devices.
