Mueller Lecture in the Physical Sciences to be held on March 31

Qi-Kun Xue, a professor of physics at Tsinghua University in China, will present the 2011 Mueller Lecture in Physics on March 31 at the Penn State University Park campus. The free public lecture is sponsored by the Eberly College of Science and the Department of Physics.

This lecture, intended for a general audience, is titled "Molecular Beam Epitaxy-Scanning Tunneling Microscopy," and will be held at 4 p.m. in 117 Osmond Laboratory. A social will be held preceding this lecture, starting at 3:30 p.m. in the Davey Laboratory/Osmond Laboratory overpass.

Xue's research interests include scanning-tunneling microcopy and spectroscopy, molecular-beam epitaxy growth of semiconductor and metal thin films, low-dimensional superconductivity, molecule-based spintronics, topological insulators, and quantum-size effects in low-dimensional structures. Xue received his doctorate degree in condensed-matter physics from the Institute of Physics of the Chinese Academy of Sciences (CAS) in 1994. From 1994 to 2000, he worked as a research associate at the Institute for Materials Research at Tohoku University in Japan, and as a visiting assistant professor in the Department of Physics at North Carolina State University. He became a professor at the Institute of Physics at CAS in 1999 and was elected a member of the Chinese Academy of Sciences in 2005. In that same year, he moved to Tsinghua University in China. In addition to being a professor at Tsinghua University, he also is the chair of the Department of Physics and the dean of the School of Sciences.

The Erwin W. Mueller Memorial Lecture in Physics honors the late Erwin W. Mueller, who was a member of the Department of Physics at Penn State from 1952 until his death in 1977. Among his many accomplishments were important contributions to the field of microscopy. He invented the field ion microscope, which enabled him to be the first person to see individual atoms. He also invented the atom-probe field ion microscope, an instrument that can aim at a single atom in a crystal surface, separate it from surrounding atoms, and identify it by mass. He was the first person at Penn State awarded the National Medal of Science. For more information about the lectures, contact Cheryl Ann Wagner at 814-865-7534.
