Education and early career
Li received a B.S. degree with the highest honor in Applied Physics from Huazhong University of Science and Technology, China, and a M.S. degree in Electrical Engineering from Lehigh University, UK. He also holds a Ph.D. degree in Electrical Engineering with minor in Physics from Georgia Institute of Technology, USA.
Areas of expertise and current scientific interests
Professor Li is interested in the investigation of 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.
Professor Li’s research activities are highly interdisciplinary. They involve electrical engineering, applied physics, material science, chemical engineering and other related disciplines.
Why wide bandgap semiconductors?
Semiconductor technology is arguably the most important technology which transforms the human beings into the digital age today. From homes, companies, organizations, government, to outer space, there are trillions of semiconductor devices empowering every aspect of the society.
The wide bandgap semiconductor is an emerging branch of the overall semiconductor field. It has unparalleled material properties that can be made into cutting-edge solid state ultraviolet to infrared light sources, solar cells, high power devices, high-frequency devices, and sensors. One of the good examples is GaN LED which produces nearly all the light in the evenings at KAUST and in many places all over the world. The Nobel Prize in Physics 2014 is a direct result of R&D in GaN LED. However, it is just the beginning for the wide bandgap semiconductors. There are still enormous research and commercialization opportunities for anyone who is working in the field. Because of its importance, the wide bandgap semiconductor is often referred to as the third generation semiconductor. My group is all into discovery new science and develop cutting-edge technologies in this promising field.
I was attracted to KAUST because KAUST offers strong financial support so that I can spend sufficient meaningful time advising students and discussing ideas. Saudi Arabia is also transforming into a modern society, leading to numerous opportunities—I have witnessed a similar process in China since the 1980s, with huge opportunities generated for the people.
KAUST is also such a beautiful place, with the Red Sea just steps away—the campus is perfectly designed, making commuting, living and working a great pleasure. Every day I am learning new ideas and knowledge from discussions, seminars, and conferences on campus. I have also had ample opportunities to travel to different conferences and institutions to build academic connections and collaborations.
