Abstract
Two-dimensional analysis of the turn-on characteristics of GaAs MESFETs is made in which deep donors 'EL2' in the semi-insulating substrate and surface states are considered. It is found that abnormal current overshoot due to EL2 can be seen when the off-state gate voltage is deeply negative. This is because in such a case electrons are depleted also in the semi-insulating substrate in the OFF state, and the corresponding ionized EL2 density NEL2+ around the channel-substrate interface can be much higher than in the ON state.
