We present a performance enhancement evaluation of n þ doped graded InGaN drain/source regionbased HfO2/InAlN/AlN/GaN/AlN on SiC metal-oxide-semiconductor high electron mobility transistor (MOS-HEMTs) with a T-shaped gate. Impact on the device characteristics with the inclusion of a HfO2 surface pas...
