摘要：

In this paper, an ultraviolet (UV) photodiode in p-n heterojunction configuration is fabricated from TiO2 nanorods hydrothermally deposited on p-type silicon substrate. Under UV illumination condition, the heterojunction photodiode shows superior UV detection capability achieving a photoresponsivity of 1.41 A/W, a photosensitivity of 80 and a detectivity of 8.32 x 10(11) Jones with a quick response speed of 25 ms. More significantly, the presented fabrication approach can be applicable to other metal-oxide semiconductor based optoelectronic devices.
