The authors report the growth of TiO 2 nanowires by heating the Ti/glass template and the fabrication of a TiO 2 nanowire photodetector (PD) by depositing interdigitated contact electrodes. It was also found that the fabricated TiO 2 nanowire PD was visible-blind with a cutoff wavelength around 390 nm. Compared with conventional film-type TiO 2 PDs, it was found that we could achieve a 10 times larger photocurrent from the TiO 2 nanowire PD. It was also found that dynamic response of the TiO 2 nanowire PD was stable and reproducible with an onoff current contrast ratio of around 100. Furthermore, it was found that UV-to-visible rejection ratio observed from the TiO 2 nanowire PD was also larger, as compared to conventional film-type TiO 2 PDs.
