| Abstract(in English) | Effects of substrate traps on turn-on characteristics of GaAs MESFETs are studied by two-dimensional simulation. When the off-state gate voltage is more negative than the threshold(pinchi-off)voltage, abnormal current overshoot and subsequent slow transient are observed for the case with undoped semi-insulating substrate including an electron trap : EL2. Even if the surface-state effects are pronounced to show the gate-lag, the drain current may show the overshoot behavior at relatively early periods. The case of Cr-doped substrate with a hole trap : Cr is also sidcussed. |
