We have studied the evolution of the surface topography of neon-bombarded gold films, from the initial stages of sputter damage to the removal of several layers. Energy-dependent sputter yields and crater size distributions are derived from scanning tunneling microscope (STM) images which show the progressing surface erosion. A surprising duality in the behavior of surfaces prepared by deposition of atoms (growth) and ‘‘deposition of vacancies’’ (erosion) is revealed.
