Gate- and drain-lag phenomena are investigated in AlGaAs-InGaAs pseudomorphic HEMTs by comparing experimental transient and pulsed characteristics with simulated ones. A consistent interpretation for experimental data is provided, relying on the assumption that acceptor-like surface traps are present at the ungated surface between gate and source/drain contacts.
