Surface texture induced by heavy ion bombardment: Ion reflection analysis

The structure of the surface of a polycrystalline platinum target bombarded with krypton ions was tested using the effect of ion reflection by atomic pairs. It was shown that the facets for which the local incidence angle is smaller than the incidence angle at which the knocking-out of one atom from...

Description
Summary:The structure of the surface of a polycrystalline platinum target bombarded with krypton ions was tested using the effect of ion reflection by atomic pairs. It was shown that the facets for which the local incidence angle is smaller than the incidence angle at which the knocking-out of one atom from the atomic pair is possible will not be etched. After a long ion irradiation time, only crystallites which have a prism shape with an eroded top will protrude.
