Electrical & Computer Engineering
Compound semiconductor materials for electronic and opto-electronic devices in electronic systems and optical communications.
Professor Tu's fields of research include gas-source molecular beam epitaxy (MBE) of III-V compound semiconductor heterostructures for electronic and opto-electronic applications. He was the first to set up gas-source MBE systems in U.S. universities. With these systems, his group is able to advance the capability of MBE into arsenide / phosphide / nitride-based heterostructures and selective-area regrowth on patterned-and-etched substrates to improve performance of electronic and opto-electronic devices.
Charles Tu is a professor of electrical and computer engineering (ECE) at the UCSD Jacobs School of Engineering. He joined the UCSD faculty in 1988, and was appointed associate dean of the Jacobs School in 2004, after serving from 1999 to 2003 as chair of the ECE department. Tu's research interests include novel III-V compound semiconductor materials and bandgap-engineered structures for electronic, optoelectronic and other devices. He was a distinguished member of AT&T Bell Laboratories technical staff from 1980 to 1988. Tu is a Fellow of the IEEE (2002), the American Physical Society (2002), and the AVS Science and Technology Society (2004). He earned his Ph.D. in Applied Physics from Yale University in 1978 and has authored more than 300 technical papers. Since 1995 Tu has been an adjunct professor at Korea's National Kwang-ju Institute of Science and Technology.
