Dual-functional ultraviolet photodetector with graphene electrodes on AlGaN/GaN heterostructure

Abstract A dual-functional ultraviolet (UV) photodetector with a large UV-to-visible rejection ratio is presented, in which interdigitated finger-type two-dimensional graphene electrodes are introduced to an AlGaN/GaN heterostructure. Two photocurrent generation mechanisms of photovoltaic and photoc...
