Abstract

Vacuum surface and gamma-ray irradiation effects on photodiodes and LED’s play a significant role in the optical and electronic properties of these diodes, particularly in a space environment, which involves both ionizing radiation as v^ll as vacuum conditions. Exposure of GaAs light emitting diodes (LED’s) to vacuum gives rise to desorption of surface-adsorbed gases and subsequent free charge diffusion and redistribution that significantly alter diode properties. Changes in photodiode properties due to vacuum operation and y-radiation have also been observed. These changes are given, and a model explaining the changes is presented.
