摘要

The authors report the growth of TiO ₂ nanowires by heating the Ti/glass template and the fabrication of a TiO ₂ nanowire metal-insulator-semiconductor (MIS) photodetector (PD). Compared with a TiO ₂ nanowire metal-semiconductor-metal PD, it was found that we could achieve a photocurrent 29 times larger. It was also found that the dynamic response of the TiO ₂ nanowire MIS PD was stable and reproducible with an on/off current contrast ratio of around 180. With an incident light wavelength of 390 nm and an applied bias of 5 V, it was found that the measured responsivity of the PD was 2.46×10 ^-3 A/W. Furthermore, the noise equivalent power and the detectivity of the fabricated TiO ₂ nanowire MIS PD were 7.49 × 10 ^-12W and 8.86 × 10 ¹¹cm.Hz ^0.5W ^-1, respectively.
