Molecular dynamics simulation of the interaction of low-energy Ar ions with polyethylene and pentacene surfaces
The normal bombardment of bulk polyethylene and pentacene crystals with 100-eV Ar ions has been investigated by molecular dynamics simulation using the many-body potential for covalent bonds. Polyethylene targets with and without chain folds on the surface have been used. The sputtering yield and changes in the atomic structure of targets are discussed.
