A model for surface damage in ion-irradiated solids

Research output: Contribution to journalArticlepeer-review


A model for defect production near the surface of an ion-irradiated solid is developed based on the concept of local melting. The model shows that, as heat diffuses radially outward from the track of an ion, a cylinder of melt is created, and owing to the large volume change on melting, pressure is developed in the liquid. Unlike displacement cascades in the interior of the crystal, the pressure is relieved by the viscous flow of liquid through the surface. The results of the model are compared to results from molecular dynamics simulations and to experimental observations.
