Dr. Zhang received B.S. and M.S. degrees in physics from the Nanjing University
of Science and Technology in 1982 and the Chinese Academy of
Science in 1986, respectively. He was on the faculty of Shanghai Jiao Tong
University between 1986 and 1989. He received his Ph.D. in physics
from Syracuse
University in 1994, spent 3 years as a postdoctal
fellow at Oak
Ridge National laboratory/the University of Tennessee prior to joining the Florida International University as a
faculty member in 1998. Starting from 2009, he became a full professor in
physics at Louisiana
State University. |

Research
Interest: Experimental
Condensed Matter Physics
One grand challenge in
condensed matter physics and materials science is to understand the
remarkable properties emerging from complex correlations of atomic and
electronic constituents, and to control these properties for technological
applications. The complexity in many novel materials is directly responsible
for their tenability and consequently their practical functionality. In many
cases, Creating surfaces, interfaces, ultra-thin films, and artificial
superstructures add the additional twist of “man-made” dimensions, approaching
the quantum phenomena of correlated electrons with broken symmetry and
reduced dimensionality. My main research interest is in
exploring novel properties of complex materials like transition-metal oxides
by the effects of broken symmetry, reduced dimensionality and spatial
confinement, and by controlling lattice strain and chemical composition. The
research include growing artificially structured configurations of complex
materials like transition-metal oxides with atomic scale precision and in-situ
comprehensive characterization on lattice structure, chemical composition,
electronic and magnetic properties. |
