MIR@W-Day and CSC One-Day Workshop
Centre for Scientific Computing, University of Warwick
Organiser: R.A. Roemer (Warwick)
Understanding how charge is transported in solids, liquids, molecules, in nanostructures - artificial or self-assembled -, in biological systems or chemical substances has always been the key to their eventual use as devices. For example, the current understanding of transport in semiconductor devices is at the heart of the continuing growth in the IT and computer sector as well as the consumer electronics market.
At everyday lengths and time scales, charge transport appears quite well understood, governed by Coulombs laws and Newtons equations. But when we reduce the system size or enhance the effects of the quantum mechanical nature of the system, say, by reducing the temperature, interesting and new physics emerges. A most interesting example of a wire-like structure is provided by the double-helix of deoxyribonucleic-acid (DNA), the carrier of genetic information. In order to express its genetic contents it must interact not just chemically with other bio-molecules - electronic or ionic transport processes should be important as well. From a technological point of view, DNA could be engineered to act as a molecular wire or a transistor with potential nanotechnology applications. It is equally intriguing to medical scientists because some DNA repair mechanisms have been reported to include processes involving electrons, for example, skin cancer and other skin related conditions. It is therefore relevant to use methods developed to describe electronic transport in physics also to this biologically relevant structure and in particular, investigate whether a connection between its biological function and electronic properties can be established.
It is only recently that these advances in DNA research, combined with tremendous progress in nano-structure experimentation techniques, have made investigations of DNA transport properties feasible. However, while important experimental and theoretical benchmarks have already been established, it is not yet even clear whether DNA should be characterized as a metal, a semiconductor or an insulator. Furthermore, the theoretical models also differ widely. The present conference will bring together some of the laeding players in the field and thus contribute towards establishing the necessary ground work.
This preliminary programme is still subject to major changes.
