Kink phenomena in GaAs MESFETs are studied by self-consistent 2-D simulation. The kinks are explained by impact ionization of holes and the following hole trapping (or hole accumulation) in the substrate rather than by direct gate breakdown. The kink-related backgating effect is also reproduced by our simulation, which is qualitatively consistent with a recent experimental finding.
