Influence of radiation effects on the electrical characteristics of photodetectors
MetadataShow full item record
Radiation effects in photodetectors (photodiodes) induced by various sources and fluences were studied in this paper. The influence of irradiation was determined by forward current-voltage (I-V) measurements of electrical characteristics. From I-V data, the ideality factor, saturation current, and series resistance were determined as a function of irradiation. Possible degradation of the electrical performance of photodetectors induced by irradiation was studied via ideality factor and its connection with the current transport mechanisms in these devices.
