Abstract

This study theoretically demonstrates that the gate-lag in recessed-gate GaAs MESFETs may not be completely suppressed when the deep-acceptor-like surface state acts as a hole trap, because the thickness of surface depletion layer can change much by the applied gate voltage. Abnormal current overshoot arise due to deep traps in the substrate when the off-state gate voltage is deeply negative.
