Abstract

Characterization of UV photodetector on ultra thin TiO₂/diamond has been carried out. TiO₂ film has been deposited on single crystal diamond surface through radio frequency magnetron sputtering method, upon which interdigitated electrodes were patterned to form the photodetector. The photodetector showed an obvious response selectivity between UV and visible regions, and exhibited two response peaks at around 225 nm and 290 nm which stemmed from the response of diamond and TiO₂, respectively, indicating a stretch of detection range of pure diamond or TiO₂ photodetector. When TiO₂ film became thinner, the transient response performance was improved.
