摘要: The ultraviolet (UV) photoresponse properties of a n-ZnO nanorods/p-diamond heterojunction were investigated by studying the dark and photo I–V characteristics. It shows typical rectifying behavior with rectification ratio 3.2 8.8 at 5 V for current photocurrent, respectively. turn on voltage under UV illumination is three times lower than that ideality factor device decreased. forward more 4 higher one 10 whereas leakage little increase −10 V. electrical transport behaviors are both photocurrent. photogenerated charges their transfer processes analyzed surface photovoltage (SPV) measurements.
