The major focus of my current research is nanotechnology. One project involves computing the binding energies of atoms on the sidewalls of a carbon nanotube. For hydrogen we have determined the binding energy as a function ofcoverage. We use the ONIOM approach where part of the system treated using a high level ab initio approach and the rest of the system is treated using a lower level of theory. We are also investigating the idea of using atoms bonded to a surface to store data. Recently we began to study conducting molecules. We are beginning the study of metal-metal and metal-CO bonds as input into the effort modelling the growth of carbon nanotubes on small metal particles.
