Impact-induced desorption of large molecular structures from graphitic substrates

Research output: Contribution to journalArticlepeer-review


We use molecular dynamics computer simulation to show how the impact of a C60 molecule on a graphite surface can cause an acoustic wave across the surface of the substrate that is strong enough to desorb a neighbouring C60 molecule that has already been adsorbed. This could have potential implications for experimentalists attempting to grow fullerene-based structures on graphite-like materials using an energetic deposition technique. It suggests that unlike normal growth conditions, where sticking probabilities are the principle concern, an extra problem of deposition induced desorption may further slow a growth process.
