Abstract:

The interactions of low energy ions with surfaces have been studied using surface science techniques. The energy range studied is from about 1 eV-5 keV, the ions involved are rate gas ions He, Ne, Ar and reactive ions such as N2, N, C, CO, and O, and the surfaces included compounds such as K2TiF6, K2NbF7, K2TaF7, and boron nitride BN and elemental materials such as graphite, gold, magnesium, nickel, boron, Si100, and W211. The phenomena investigated included scattering, recoiling, ion induced surface damage decomposition, oxidation, nitridation, chemisorption, inelastic collisions with emission of photons and electrons, scattered and recoiled ion fractions, collisional dissociation, and the dynamics of low energy collisions. The results are contained in six scientific publications in refereed journals.
