Resumen en inglés Here, we study a simulation model of In0.17Al0.83N/GaN passivated high electron mobility transistors (HEMTs) on SiC substrate. The research focused systematically on the effect of AlN interlayer on the electronic and electric characteristics. The 2D-electron gas density of In0.17Al0.83N/AlN/GaN HEMTs is investigated through the dependence on various AlN layer thickness. We report calculations of I-V characteristics, with 1.5 nm AlN thickness. We find the highest maximum output current of 1.81 A/mm at Vgs = 1 V, and more than 450 mS/mm as a transconductance peak. The Results are in agreement with experimental data.
