Desorption of Excited Neutrals from Surfaces via an Electron Attachment Mechanism.

Abstract

A detailed comparative investigation of OH and OH+ desorption from OH/TiO2, H2O(s), and H2O(g) indicates four different mechanisms are responsible for the OH desorption. Two of these involve a resonant excitation-dissociative attachment-mechanism. The other two mechanisms involve non-resonant excitation or ionization processes similar to that responsible for the OH+ desorption. Keywords: Photon-stimulated desorption; photo-dissociation; fragmentation; electron stimulated desorption; negative ions; dissociative attachment.
