AlGaN/GaN-based multi-channel epitaxial structure with an ultra-low 2DEG density and superior carrier transport performance

AlGaN/GaN-based multi-channel epitaxial structure with an ultra-low 2DEG density and superior carrier transport performance

In this work, the relationship between two-dimensional electron gas (2DEG) density and electron velocity in AlGaN/GaN-based single-channel and multi-channel structures has been studied through I-shape test structure and pulsed I – V measurements. With an optimized epitaxial design, a multi-channel s...
