GaN-based high-electric-mobility transistors(HEMTs) have been investigated thoroughly because of their promising applications in high-frequency,-voltage, and-power applications. However, the theoretical material limit prevents conventional single-heterostructure GaN HEMTs from achieving high performance despite numerous efforts [1–3].
