Ultraviolet Detector Based on ZnO/Diamond Film Heterojunction Diode
-axis oriented n-type ZnO films were grown on the p-type fresstanding diamond(FSD) substrates by radio-frequency (RF) magnetron sputtering method. The effects of the sputtering power on the pro-perties of ZnO films were studied. Current-voltage (
I-V
) characteristics of the ZnO/diamond heterojunction were examined by a semiconductor characterization system and the results showed a distinct rectifying characteristics with a turn-on voltage of about 1.6 V. The ZnO/diamond heterojunction diode was also used for ultraviolet(UV) detector application and the detector showed a significant discrimination between the UV light and the visible light under reverse bias conditions.
