Abstract
Wide-bandgap semiconductors such as III-nitrides (AlN, GaN and their
compounds) have superior optical, electronic and structural properties for
optoelectronics and electronics in general. In the past decades, the development of
III-nitride optoelectronics including blue light-emitting diode (LED) and laser has
led to revolutions in many industries as partially reflected by the Nobel Prize in
Physics 2014. Despite these progresses, there are still tremendous opportunities to
explore III-nitride semiconductors for applications in the shorter wavelength range
(i. e. ultraviolet, or UV). For instance, the compact and reliable UV LED is expected
to dramatically innovate the entire disinfection industry. The UV laser can create
numerous opportunities in data storage, non-line-of-sight communication, Raman
spectroscopy, and bioagent detection. This seminar will focus on the latest
breakthroughs and potential applications of UV optoelectronics.

Biography
Xiaohang Li is an Assistant Professor in the Division of Computer, Electrical,
Mathematical Science and Engineering (CEMSE) at King Abdullah University of
Science and Technology (KAUST). 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 at Georgia Institute of Technology (GT).
Currently, Xiaohang's research focuses on growth, fabrication and
characterization of III-nitride semiconductors for optoelectronic and electronic
devices. Previously, Xiaohang has conducted multidisciplinary research projects
related to solid state lighting, colloidal particles, ferromagnetic fluid, and water
purification at various research organizations.
Xiaohang has authored over 65 journal and conference publications. He
holds several issued and pending patents. He is an active journal reviewer. He is a
recipient of D.J. Lovell Scholarship from International Society for Optics and
Photonics (SPIE) (one recipient per year worldwide), Graduate Student Fellowship
from IEEE Photonics Society (ten recipients per year worldwide), and Edison Prize
from GT (one recipient per year). He represented GT to attend Global Young
Scientist Summit. 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 K12 students, including many underrepresented ones.
