Controlled Sputtering of Metals by Low-Energy Hg Ions

Abstract
Sputtering has been studied under well controlled conditions, i.e., low gas pressure (1 micron), defined energy (up to 300 ev) and angle of incidence of the bombarding ions, and high ion-current density (10 ma/cm2), by immersing the target in a low-pressure Hg plasma of high density created in a pool-type vacuum arc.
