Research

Our current research interests lie in the intersection of 
• Novel III-V materials and hetero-structures, and
• Photonic and electronic quantum devices.

Particularly, we explore
• III-V materials and novel devices,
• Hetero-integration of III-Vs on unconventional platforms such as graphene and silicon,
• Heat transport across/through semiconductors,
• Efficiency droop mechanisms and remedies in AlInGaN emitters, and
• Ultra-fast THz photonics/electronics.

Our work is interdisciplinary. Our alumni demonstrate strong skills in solid state physics, first principles calculations, Technology Computer Aided Design, micro/nano-fabrication, and reliability characterization and analysis of semiconductor devices. Our collaborations include on-campus resources including Materials Research Laboratory, Beckman Institute for Advanced Science and Technology, Materials Science and Engineering Department, Chemical Engineering Department, Mechanical Engineering Department, and off-campus ones including Northwestern University, University of Illinois at Chicago, Argonne National Laboratory, University of Minnesota, University of Notre Dame, Stanford University, Veeco, and IBM.

Our research team is recognized with distinguished (inter)national awards such as NSF Graduate Research Fellowship, NASA Space Technology Research Fellowship, Goldwater Scholarship, Lemelson-MIT Student Prize Graduate Finalist, National Inventors Hall of Fame Collegiate Inventors Competition Finalist, SPIE Scholarships, and CS Mantech Best Paper Award.
