Abstract

Field-emission current from titanium-oxide nanostructure is increased by ultra-violet (UV) light irradiation. The enhancement factor of the UV whose wavelength is 365 nm is larger than that of 405 nm. The increased emission current did not decrease even after stopping the irradiation until the sample is exposed to the air. This suggests that the surface cleaning is the origin of the observed current enhancement.
