Abstract

Molecular dynamics simulations have been performed to gain microscopic insight into those factors which influence the ejection due to ion bombardment of molecules adsorbed on solid substrates. The specific system modeled is a pentylidyne (C₅H₉) film adsorbed on Pt{111} and C{111}. Lowering the binding energy of the film to the substrate from 2.7 to 0.6 eV increases the total yield of ejected particles. The bombardment of the film bound by 2.7 eV results in considerable fragmentation of the C₅H₉ adsorbate while the bombardment of the film bound by 0.6 eV results in the desorption of the intact molecular adsorbate.
