资源简介:
This work reports effect of proton radiation on barrier infrared detector with cutoff wavelength of 10.5 and 12.2 m. The results indicate that proton radiation causes slow increase in dark current of the barrier infrared detector. The radiation effect on quantum efficiency of detector is not conclusive. However, the increase in dark current and decrease in quantum efficiency is slow and within acceptable level for an Earth orbit space mission.
