Patent number: 11101379Abstract: A novel design for a nitrogen polar high-electron-mobility transistor (HEMT) structure comprising a GaN/InGaN composite channel. As A novel design for a nitrogen polar high-electron-mobility transistor (HEMT) structure comprising a GaN/InGaN composite channel. As illustrated herein, a thin InGaN layer introduced in the channel increases the carrier density, reduces the electric field in the channel, and increases the carrier mobility. The dependence of p on InGaN thickness (tInGaN) and indium composition (xIn) was investigated for different channel thicknesses. With optimized tInGaN and xIn, significant improvements in electron mobility were observed. For a 6 nm channel HEMT, the electron mobility increased from 606 to 1141 cm2/(V·s) when the 6 nm thick pure GaN channel was replaced by the 4 nm GaN/2 nm In0.1Ga0.9N composite channel.Type: GrantFiled: November 16, 2017Date of Patent: August 24, 2021Assignee: THEREGENIS OF THE UNIVERSITY OF CALIFORNIAInventors: Brian Romanczyk, Haoran Li, Elaheh Ahmadi, Steven Wienecke, Matthew Guidry, Xun Zheng, Stacia Keller, Umesh K.
