Abstract :
This paper describes the PETS electrothermal simulator that is coupled to G-PISCES-2B, a drift-diffusion Poisson-current-continuity equation solver. The intention is to make users in the GaAs REL community aware of some of the consequences of the shapes of the power dissipation profiles in MESFETs, HEMTs, and HBTs. We present obligatory comparisons between measured and modeled HEMT and HBT thermal impedances, but we focus on what we can learn about thermal designs from the simulator
