Turn-on characteristics of GaAs MESFETs are simulated in which substrate traps and surface states are considered. Quasi-pulsed I-V curves are derived from the turn-on characteristics, indicating that so-called power slump could occur both due to substrate traps and due to surface states. Transient simulations of GaN MESFETs are also performed in which deep levels in a semi-insulating buffer layer are considered. So-called drain lag is shown to arise as in GaAs MESFETs. It is also shown that the power slump in GaN MESFETs could occur due to deep levels in the semi-insulating buffer layer.
