Paper Abstract

In this work, the heterostructures of III-N materials/β-Ga2O3 based on the modern polarization theory and band alignment are systematically investigated. The nitrogen (N)-polar AlN/β-Ga2O3 heterojunction is found that can form the triangle channel and hold large 2DEG density on the interface through polarization engineering. Compared with GaN-based HEMT, the proposed N-polar AlN/β-Ga2O3 HEMT with polarization-induced property can realize much larger 2DEG density, better DC and transconductance performance, as well as higher breakdown voltage.
