THE BOMBARDMENT OF GOLD FILMS BY INERT GAS IONS
Journal Article
·
· Phys. Chem. Solids
Films of gold were bombarded by nearly mono-energetic ions of helium, neon, argon, or xenon in the energy range 15 to 250 ev, and then examined in an electron microscope. The damage caused by the bombardment is found to depend markedly on the energy of the ions and the gas, and to a lesser extent on the orientation of the crystal and the ion flux density. There is a threshold energy for the ions below which no damage is detectable, and its values for neon, argon, and xenon but not helium, are consistent with a model in which a simple collision at the surface may create an interstitial gold atom below the surface. The annealing characteristics depend upon the gas producing the damage. Sputtering yields were measured; at low energies argon sputters {110} surfaces more rapidly than {111}. (auth)
