Ya-Hong Xie was born in Beijing, China. He entered the Physics Department of Peking University
in 1977. After one and a half years, he transferred to the Physics Department of Purdue
University. He obtained the B.S. degree in physics from Purdue University in 1981, and the M.S.
and Ph. D degrees in electrical engineering from UCLA in 1983 and 1986, respectively. His Ph. D
thesis research was on Si Molecular Beam Epitaxy under the guidance of Prof. Kang L. Wang.

Following graduation, Ya-Hong Xie joined AT&T Bell Laboratories (later became Bell Laboratories,
Lucent Technologies). From 1986 until 1999, he had been a member of the technical staff at the
Bell Laboratories. His research activities during this period included impurity center mediated
luminescence in Si (e.g. Er doped Si), light emitting porous Si, GeSi/Si molecular beam epitaxy,
dislocation kinetics in relaxed GeSi/Si heterostructures, strain induced surface roughening in
GeSi epitaxial thin films (also known as self-assembled quantum dots), fabrication of high mobility
two-dimensional electron and hole gases in GeSi/Si, and the transport properties and device
applications of various Si-based heterostructures.

Ya-Hong Xie joined UCLA as a professor of Materials Science & Engineering in 1999. His current
research interests include the fabrication of 2D electron system in strained Si, epitaxial growth of
self-assembled quantum dots of III-V and group IV semiconductors, RF crosstalk isolation and
substrate impedance engineering for mixed-signal IC applications, and novel devices centered
around Si CMOS technology.
