Anomalous Room Temperature Diffusion of Ion-Injected Ni in Zn Targets

Abstract

It has usually been found that when energetic ions are impinging on the surface of a metal target at an energy at which the selfsputtering coefficient Se = 1 (the sputtering coefficient S being the number of atoms sputtered per impinging ion, and self-sputtering referring to sputtering of a metal by ions of the same element), the total amount of projectile material trapped in the target soon reaches a saturation value of some μgram per cm2.
