Abstract

Polarization junction platforms have high-density 2D hole gas (2DHG) and 2D electron gas (2DEG) respectively induced by negative and positive polarization charges in undoped GaN/AlGaN/GaN double heterostructures. Sheet resistance measurements in a wide temperature range (6-460 K) revealed that 2DHG and 2DEG resistances were monotonically enhanced with the temperature reduction. On the platform, monolithic operations of GaN-based devices including high-voltage n-channel (N-ch) transistors, N-ch Schottky diodes, low-voltage N-ch transistors and p-channel transistors has been demonstrated.
