Photovoltaic Properties of Titanium Dioxide Nanowires with Different Crystal Structures

Titanium dioxide(TiO2) nanowires with different crystal structures were successfully synthesized, and their charge transfer properties were further investigated by surface photovoltage(SPV), transient photovoltage(TPV) and surface photocurrent(SPC) techniques. The results reveal that both the surface states and the charge transfer rate of different TiO2 nanowires are highly dependent on their crystal structures.
