DOI: 10.1109/led.2019.2944720
Abstract: The self-aligned metal-semiconductor-metal (SA-MSM) structure was utilized to fabricate varactors on top of the AlGaN/GaN heterostructures. The SA-MSM structure minimizes the access resistance associated with 2-dimensional electron gas (2DEG), resulting in the significantly improved cutoff… read more here.
