The anatase TiO₂ nanowire arrays with 60 nm diameter and 20 nm diameter were prepared within the nanochannels of anodic aluminumoxide (AAO) template by an electrochemically induced sol-gel method. Atomic force microscopy (AFM) technique was applied to map topographic image at half-contact mode and to measure current-voltage characteristics of individual TiO₂ nanowire at contact mode. The I -V characteristics of individual TiO₂ nanowire by AFM revealed semiconductor characteristics. The bias voltage resulting in a measurable current on individual TiO₂ nanowire was much lower than that on the bulk TiO₂ materials, and its value increased with the diameter of individual nanowire decreasing.
