Ph.D. Yale University, 1978

Electronic Materials

Charles Tu was a Lecturer in the Yale Physics department from 1978-1980. From 1980-1988, he was a member of the technical staff at AT&T Bell Laboratories, Murray Hill, N.J. In 1988 he joined the faculty of UC San Diego.

Current Research

Gas-source molecular beam epitaxy (MBE) of III-V compound semiconductors heterostructures for electronic and optoelectronic applications. He set up two of the first three or four 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 device performance.  Currently his research focus is on a new class of semiconductors, dilute nitrides, for optoelectronic applications.
