Welcome to the Xing Group

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

Our research projects involve growth, fabrication and characterization of semiconductor electronic and optical materials and devices, primarily III-V nitride semiconductors, 2D crystals, steep transistors, and more recently Ga2O3, multiferroics and magnetic materials.
