Abstract
White-light-controlled resistance switching in TiO2/α-Fe2O3 composite nanorods array grown on fluorine-doped tin oxide substrate by hydrothermal process is investigated. The average length of TiO2/α-Fe2O3 nanorods is about 3.5 μm, and the average diameter is about 250 nm. The sizes of the α-Fe2O3 particles are in the range of 30 ~ 70 nm. The current–voltage characteristics of the composite nanorods array show a good rectifying property and bipolar resistive-switching behavior, and the resistive-switching behavior can be regulated by white-light illumination at room temperature. This study is helpful for exploring the multifunctional materials and their applications in nonvolatile multistate memory devices.
