  • Curve-Crossing Analysis for Potential Sputtering of Insulators

  • Journal article (peer-reviewed)abstract
    • We develop a theoretical model for the recently observed threshold for potential sputtering of LiF by slow singly and doubly charged ions. The threshold coincides with the potential energy to create a cold hole in the valence band of LiF by resonant neutralization. We calculate the level shift of the incident ion and the deformation of the valence band under the influence of the projectile. Resonant neutralization becomes possible for ions with recombination energies larger than 10 eV in agreement with the experimental findings.

  • Vertical incidence of slow Ne10+ ions on an LiF surface: Suppression of the trampoline effect
  • 2001
  • In: Nuclear Instruments and Methods in Physics Research Section B. - 0168-583X .- 1872-9584. ; 182:1-4, s. 36-40
  • Journal article (peer-reviewed)abstract
    • We present a Monte Carlo simulation of the neutralization of a slow Ne10+ ion in vertical incidence on an LiF(100) surface. The rates for resonant electron transfer between surface F- ions and the projectile are calculated using a classical trajectory Monte Carlo simulation. We investigate the influence of the hole mobility on the neutralization sequence. It is shown that backscattering above the surface due to the local positive charge up of the surface ("trampoline effect") does not take place.
