We report the studies of In0.15Al0.85N/AlN/GaN metal-insulator-semiconductor (MIS) high electron mobility transistors with a field plate (FP) and a plasma-enhanced chemical vapor deposition (PECVD) SiN layer as the gate dielectric as well as the surface passivation layer (FP-MIS HEMTs). Compared with conventional In0.15Al0.85N/AlN/GaN high electron mobility transistors (HEMTs) of the same dimensions, the FP-MIS HEMTs exhibit a maximum drain current of 1211 mA/mm, a breakdown voltage of 120V, an…
