Abstract Gallium arsenide tunnel diodes were irradiated with electrons of energy E = 2.0 MeV at room temperature. Secondary hump structures were observed in the region of 0.45 V and 0.65–1.1 V forward bias. The variation in the excess currents of diodes subjected to electronic bombardment is described on the basis of models including three levels; EB + 0.25 eV, EB + 0.55 eV, and EC−0.5 eV. Annealing of radiation-induced defects is shown to take place in two stages at temperatures of 140–180°C and 200–240°C. “Switching” and “memory” effects are observed when the current-voltage characteristics (CVC) of tunnel diodes are measured at liquid-nitrogen temperatures in darkness.
