Nanostructured carbon and nanotechnology revolution

David Tomanek

Department of Physics and Astronomy
Michigan State University
  USA  






The continuous reduction of device sizes, which is rapidly approaching the atomic level, calls for new approaches to design and test future building blocks of Nanotechnology. Computers will become the most powerful tool to interpret what happens on the nanometer scale, where as I will illustrate, structures of carbon may become stronger than steel, yet turn into quantum conductors or even efficient heat conductors.
In nanostructures that form during a hierarchical self-assembly process, even defects may play a different, often helpful role. An efficient self-healing process may convert less stable atomic assemblies into other, more perfect structures, thus answering an important concern in molecular electronics. Defects may even be used in nano-scale engineering to form complex systems such as carbon nanotube junctions, nanotube peapods, or all-carbon magnets.
In this presentation, I will show how some of these challenging problems can be most efficiently addressed in simulations on recently available massively parallel supercomputers.

Brief Bio:

David Tomanek is a leading expert in the development and application of numerical techniques for structural, electronic, and optical properties of surfaces, low-dimensional systems and nanostructures, computer simulations of fullerenes, nanotubes, ferrofluids, metallic and magnetic clusters. He received his M.Sc. (Diploma) in theoretical physics 1979 from the University of Basel, Switzerland, and his Ph.D. in 1983 from the Freie Universität Berlin, Germany. He had a research assistant position at the Freie Universität till 1985, was research associate at the AT&T Bell Labs (1985), at the University of California, Berkeley, CA (USA) (1985-1987) before joining the Physics Faculty at the Michigan State University, East Lansing, MI (USA) in 1987. He was visiting professor in numerous universities and research institutes around the world.
