Mechanisms for Excited Neutrals and Negative and Positive Ion Desorption from Surfaces.

Abstract

In this review we summarize and generalize the results of a recent detailed comparative investigation of OH*, OH+, and H+ desorption from OH/TiO2, H2O(s), and H2O(g), and O- and O+ desorption from O/W and O/Mo(10). Two mechanisms for O- and OH* desorption have been proposed which were not revealed in the positive ion desorption yields. These additional electron attachment mechanisms are placed in the context of the previously proposed ionic desorption mechanisms and are discussed in detail. Keywords: Photon simulated desorption; photo-dissociation; fragmentation; electron stimulated desorption; dissociative attachment.
