摘　　要：We used polarized surface photovoltage spectroscopy (PSPS) to study the photovoltage response of TiO\-2 single crystal (001) surface. Besides a band\|band transition at 355 nm and a indirect transition at 410 nm, we observed a new photovoltaic response at 380 nm in the PSPS spectrum which was assigned to the transition with relation to the surface state. Under different polarized directions, the intensity of photovoltaic responses at 380 nm and 410 nm changed regularly, which proved that the two transitions were interrelated to the atomic arrangement on the TiO\-2 single crystal (001) surface.We used polarized surface photovoltage spectroscopy (PSPS) to study the photovoltage response of TiO\-2 single crystal (001) surface.
