Abstract
Hot-carrier degradation effects are investigated in AlGaAs/GaAs HFETs by coupling measurements and two-dimensional device simulations. It is shown that only a simultaneous, localised increase of defects at the gate-drain recess surface and channel-buffer interface can thoroughly account for the observed post-stress device behaviour in terms of drain saturation current decrease, reverse gate current increase, gate-lag enhancement.
