A high-performance fast response deep ultraviolet (UV) photodetectors with interdigitated Ti/Au planar electrodes using a lithography technology has fabricated on homoepitaxial diamond. The device shows a high ultraviolet photocurrent at 213 nm, which is eight orders of magnitude higher than the dark current at the bias voltages of 30 V. In addition, the time-resolved photoresponse measurements using a mechanical method and a pulsed 213 nm laser show that a good cycling, low persistent…
