Characterization and simulation of AlGaN barrier structure effects in normally-off recessed gate AlGaN/GaN MISHEMTs

Characterization and simulation of AlGaN barrier structure effects in normally-off recessed gate AlGaN/GaN MISHEMTs

The objective of this study is to optimize the trade-off between threshold voltage (V _TH ) and maximum drain current (I _D,max ) in recessed gate AlGaN/GaN metal insulator semiconductor high electron mobility transistor (MISHEMT) using atomic layer etching (ALE) technology, with technical computer-...
