FOCUS ON: Huili (Grace) Xing- Cornell University (XING RESEARCH GROUP)
Huili (Grace) Xing
Dept: Electrical and Computer Engineering
Title: Richard Lunquist Sesquicentennial Professor
Biography: I got my Bachelor Degree in Physics from Peking University. After that, I pursued a Master Degree in Material Science and Engineering at Lehigh University. Wanting to work with devices that use wonderful material properties, I went to the University of California at Santa Barbara for my Ph.D. and eventually had my degree in Electrical Engineering. From 2004 to 2014 I was a faculty at the University of Notre Dame. I moved to Cornell in 2015. Research Interests: The topics I work on now can be loosely categorized into 4 areas, supported by DoD, NSF, SRC and Doe.1). GaN based devices. The current projects include GaN power diodes and transistors, AlN/GaN ultrascaled high electron mobility transistors for high-speed high power applications, polarization doping for p-type in UV optoelectronic devices, negative differential resistance and plasma based THz sources for biomedical imaging and spectroscopy, wafer fused enabled hybrid structures. 2). nanowire enabled devices, including InGaN nanowires for high efficiency green emission and solar cells, II-VI nanowires for polarization sensitive wide spectrum photodetection etc. 3) 2D crystal materials and devices. We investigate van der Waals epitaxy, carrier electrostatics and transport, optoelectronic responses, p-n junctions and heterostructures, field modulation and tunneling, metamaterials and THz applications, graphene physics and devices. We investigate graphene based metamaterials for THz applications, lateral bandgap engineering in graphene, carrier electrostatics and transport, and optoelectronic responses, p-n junctions, field modulation and tunneling phenomena. 4) steep slope transistors for high-efficiency logic and RF electronics, especially tunnel FETs. We pioneered design, fabrication and characterization of III-V TFETs. Our current focus is 2D-crystal based steep slope transistors: the Thin-TFETs, tunneling field effect transistors for high efficiency logic electronics.
