报告提纲
RMG pre-exascale code for very large electronic structure and quantum transport calculations with full DFT accuracy wwww. rmgdift. org
▷Scales well on CPU-GPU (pre)-exascale architectures, works efficiently on desktops and clusters.
▷New eigensolver for electronic structure calculations.
▷Multi-terminal capability enables full-device simulations
▷Can handle -50k atoms
Nanotube-based DNA polymerase nano circuits: potential for all electrical DNA sequencing
Designed a novel class of nanoscale devices with negative differential resistance (NDR)
▷Tunneling at nanoscale is a major issue: requires unconventional device design
▷Novel, experimentally-realizable, atomically-precise NDR structures have been designed and fabricated
▷The multi-segment design may apply to other materials, such as MoS2, and WS2
个人简介
Professor Bernholc received his PhD in 1977 from the University of Lund, Sweden, after spending parts of 1975 and 1976 at the IBM T. J. Watson Research Center in New York. He was a Postdoctoral Fellow at the IBM Watson Center 1978-80 and a Senior Physicist at Corporate Research Laboratories of Exxon Research and Engineering Company 1980-86. Bernholc joined NC State University in 1986 as an Associate Professor, became Full Professor in 1990 and Drexel Professor in 2000. In 2004, he formed the Center for High Performance Simulation (ChiPS) at NCSU, of which he is the first Director. Since 2002, he also serves as a Visiting Distinguished Scientist at Oak Ridge National Laboratories.Prof. Bernholc is working in several subfields of theoretical condensed matter and materials physics.
