Biography
Prof. Bernholc joined NCSU's Physics Department in 1986.
Dr. Bernholc obtained a B.S. degree with a double Major in Physics and
Mathematics in 1973 and a Ph.D. in Physics from University of Lund, Sweden
in 1977. He was a Postdoctoral Fellow at IBM T.J.
Watson Research
Center 1978-80 and a
Senior Physicist at Corporate Research Laboratories of Exxon Research and
Engineering Company 1980-86.
Research Activities
Prof. Bernholc is working in
several subfields of theoretical condensed matter and materials physics. In
the area of semiconductors, he has contributed significantly to the
theory of defects, impurities, and diffusion, semiconductor surfaces and
steps, and surface optical response. In the emerging field of fullerenes,
contributions include predictions of fundamental properties of solid C60
soon after its discovery. For nanotubes, the primary growth modes
were uncovered and their extreme strength – over 10 times greater
than steel at one sixth the weight – was predicted through
simulations. Another important area of research is new methodology
for electronic structure calculations, using advanced mathematical
techniques and harnessing the power of parallel computers. A real-space
multigrid method, developed at NCSU, enables ab initio studies of very
large systems. It has been used extensively in large-scale simulations of
semiconductors, nanotubes and biomolecules, and in studies of quantum
transport in nanoscale systems.
Current research focuses on
nanoscale science and technology, nano and molecular electronics, novel
nanostructured and bio-inspired materials, O(N)
electronic structure and quantum transport methods, multilevel
acceleration in electronic structure calculations, multiscale methods, and
scalable parallel computing.
Prof. Bernholc has co-authored
over 200 papers and 175 invited talks at conferences, edited three books,
and has given over 70 seminars and colloquia at Universities and Research Centers. Illustrations from his work
appeared on the covers of Physics
Today, Physics World, Science, Science News, and Science
and Engineering Indicators. He helped organize over 50 conferences and
symposia, and co-chaired workshops on Recent
Developments in Electronic Structure Algorithms; CECAM's Grid, Multigrid and Wavelet Methods in Electronic Structure
Calculations, and NATO's Multiscale
Computational Methods in Chemistry and Biology. He is listed in Who's Who in America and
Who's Who in the World. He was elected Chair of the Division of
Computational Physics of the American Physical Society and served on
numerous government panels and committees. He currently chairs the
Scientific Advisory Board of the Center
for Nanophase Materials Science at ORNL.
