Crystallography and surface morphology of ion-irradiated silver

Investigations are performed to explore the surface morphological and crystallographic changes induced by the irradiation of laser-produced copper ions on 4N pure polished silver samples under vacuum (∼10−3 torr). The morphology was changed a great deal, with prominence in sputtering, hill and crater formation. Variation in grain size, dislocation line density and strain are the major observed crystallographic changes.
