2019 – UV degradation anaylsis of SiC and AlGaN based UV photodiodes
Dr. Niklas Papathanasiou, sglux GmbH, Berlin, Germany
Abstract
SiC and AlGaN based UV photodiodes had been irradiated by Hg medium pressure lamps for 90 hours and a UV irradiation intensity of 60mW/cm². The SiC photodiodes showed no measurable degradation whereas the AlGaN photodiodes lost 80 % – 85 % of sensitivity.
