A classical dynamics study of carbon bombardment of graphite and diamond

Abstract
Molecular dynamics simulations have been performed for normal incidence carbon bombardment of diamond {100}, diamond {111} and graphite {1000} using a many-body potential formalism and bombardment energies in the keV/sub-keV range in order to examine the ejection of atoms from the crystal. Energy and angular distributions of ejected material are calculated with an analysis of the important ejection mechanisms, including molecular ejection.
