Solar-blind metal-semiconductor-metal (MSM) photodiodes based on MOCVD-grown Al0.6Ga0.4N template have been fabricated and tested. AlGaN detector samples were fabricated using a microwave compatible fabrication process. Optical transmission, current-voltage, spectral responsivity, and temporal pulse response measurements were carried out. The fabricated devices had very low leakage current and displayed true solar-blind response with ∼255 nm cutoff wavelength. © IEE 2005
