Welcome to the Xing Group

Dr. Huili (Grace) XingPrincipal Investigator
Dr. Huili (Grace) Xing 

Our group research can be loosely grouped into three areas: GaN electronic and optoelectronics, steep transistors, and 2-D crystals. The semiconductors we work with include GaN, convential III-Vs, Si, graphene and other 2D crystals.
