Interface engineering for GaN HEMTs
The junctions formed between the metal contact and semiconductors, gate dielectrics are crucial components of GaN based electronics and optoelectronics.
Overview
Abstract
The junctions formed between the metal contact and semiconductors, gate dielectrics are crucial components of GaN based electronics and optoelectronics. However, owning to lattice mismatch and chemical interaction, the interface quality between these materials are poor which can severely impact the device performance. We studied the fundamental physical property of Al2O3/GaN and also proposed to alleviate the interface problems by creating a vdW gap between two dissimilar materials.
