Abstract :
2-D simulation of backgating effect in GaAs MESFETs is made in which impact ionization of carriers and deep donors “EL2” in the substrate are considered. The kink-related backgating is reproduced, which is qualitatively consistent with recent experiments. The mechanism is attributed to the change of EL2´s nature by capturing holes which are generated by impact ionization and flow into the substrate
