Dynamics of Hyperthermal Energy Ion-Surface Collisions: Dissociative and non-dissociative Scattering of Ethanol cations from a Self-Assembled Monolayer Surface of Fluorinated Alkyl Thiol on Au (111)

Abstract

Dissociation and inelastic scattering of ethanol molecular ions from self-assembled monolayers (SAM) surface of fluorinated alkyl thiol on an Au (111) monocrystal have been studied at 28.9 and 52.9 eV collision energies. A single dynamics mechanism for quasi0inelastic scattering was found at both energies. Ions recoil nearly parallel to the surface with very small kinetic energy losses of the order of
