Abstract
This work investigates, through the use of numerical drift-diffusion simulations, the hot electron degradation mechanisms of power AlGaAs/GaAs HFETs. The experimentally observed degradation modes can be consistently explained by a negative charge storage at the device surface over the gate-drain access region.
