Characteristics of photodetectors with TiO2 nanorod arrays
TiO2 is one of most widely studied and important materials for science application. A photodetectors (PDs) with TiO2 nanorod arrays (TNAs) has been fabricated and characterized in this work. We report that the UV response of such a PDs has been enhanced about 4 orders of magnitude. This giant enhancement in photoresponsivity can be attributed to TNAs, because TNAs provide a directed path for electrical transport and increase optical absorption. The results indicate that TNAs are useful and attractive in the application of UV detectors.

Abstract

TiO2 is one of most widely studied and important materials for science application. A photodetectors (PDs) with TiO2 nanorod arrays (TNAs) has been fabricated and characterized in this work. We report that the UV response of such a PDs has been enhanced about 4 orders of magnitude. This giant enhancement in photoresponsivity can be attributed to TNAs, because TNAs provide a directed path for electrical transport and increase optical absorption. The results indicate that TNAs are useful and attractive in the application of UV detectors.
