Al Rich AlGaN Based APDs on Single Crystal AlN with Solar Blindness and Room Temperature Operation
We demonstrate Al rich AlGaN based APDs grown on AlN substrates capable of high sensitivity at room temperature with ambient lighting rejection showcasing the advantage over Si and Ge based detectors. APDs are operated in linear gain region with maximum gain exceeding 1100.
