Xiaohang Li, Ph.D.

Principal Investigator
​Assistant Professor​​​​​​​​​​


​​Dr. Xiaohang Li is an Assistant Professor of Electrical Engineering in the Division of Computer, Electrical, Mathematical Science and Engineering (CEMSE). He received the B.S. degree with the highest honor in Applied Physics from Huazhong University of Science and Technology and M.S. degree in Electrical Engineering from Lehigh University. He received the Ph.D. degree in Electrical Engineering with minor in Physics at Georgia Institute of Technology. 

Currently, Prof. Li’s research focuses on growth, fabrication and characterization of III-nitride semiconductors for optoelectronic and electronic devices. Previously, he has conducted multidisciplinary research projects related to solid state lighting, colloidal particles, ferromagnetic fluid, and water purification at various research organizations. He has authored >100 journal and conference publications. He holds several issued and pending patents. Most notably, he has made significant contributions in the development of deep UV semiconductor lasers where he was the first to demonstrate low threshold lasers on the practical sapphire substrates. He is an active journal reviewer for prestigious journals such as Nature Photonics, Applied Physics Letter and Optics Express. 

He served as president and treasurer of IEEE Photonics Society chapter at Lehigh University. He has been a guest blogger for Edison Innovation Foundation as well as a teacher and mentor for undergraduate, graduate and K-12 students, including many underrepresented ones. He is serving on the Crystal Growth committee of the International Workshop on Nitride Semiconductors​ and the Group-III Nitrides​ committee of the Electronic Material Conference. He is the recipient of prestigious awards including D. J. Lovell Scholarship​ and IEEE Photonics Graduate Student Fellowship.​

Research Interests

​Professor Li is devoted to innovating and perfecting growth, simulation, fabrication, and characterization of III-nitride structures for next-generation devices. The devices of particular interest include LED, laser, solar cells, transistors, and sensors. Because of excellent properties of III-nitrides, these devices are expected to become the enabling technologies to revolutionize energy, communication, biochemical, biomedical, and data storage industries and many others.
