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.
