作者： Chunzhou SHI Ling YANG Meng ZHANG Hao lu mei WU Bin HOU Xuerui NIU Qian YU Wenliang LIU Wenze GAO Xiaohua MA Yue HAO School of Advanced Materials and Nanotechnology Xidian University State Key Discipline Laboratory of Wide Bandgap Semiconductor Technology Xidian University

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].
