Abstract :
In this work, for the first time, the dependence of the GaN HEMTs current collapse from the profile of the Fe-doped semi-insulating GaN buffers has been demonstrated both experimentally and by means of numerical simulations based on the SIMS measured profile of the GaN buffer Fe-doping concentration.
