Research Interests

Professor Li is interested in the ultrawide bandgap and wide bandgap semiconductors including GaN, AlN, Ga2O3, In2O3. He is focused on growth, simulation, fabrication, and characterization of next generation devices and integrated circuits including LED, lasers, high power and high frequency transistors and diodes, and stacked transistor ICs. Professor Li's research has resulted in many pioneering and cutting-edge results widely recognized and awarded by leading organizations and conferences such as IEEE, SPIE, American Association of Crystal Growth, and Edison Innovation Foundation. These devices are expected to become the enabling technologies to revolutionize energy, communication, health, sensing, and many others which are crucial for the sustainable future of human society. Professor Li's research activities are highly interdisciplinary. They involve students and researchers from electrical engineering, applied physics, material science, and other related disciplines. They are supported by state-of-the-art facilities including and not limited to: MOCVD, PLD, ALD, photolithography, e-beam lithography, PL, TEM, XRD, Raman, XPS, SIMS, RBS, supercomputer in his lab and at KAUST.
