Photon-stimulated desorption of H+ ions from OH on Ti and Cr: Comparison with bulk solid H2O
An interpretation and comparison of photon-stimulated desorption yields of H+ ions from OH on Ti and Cr and from bulk solid H2O indicate that desorption occurs through two entirely different mechanisms. The first involves in intramolecular excitation of the OH adsorbate producing a H+ yield similar to that in bulk H2O. The second involves metal core-level excitation followed by Auger decay and is an example of molecular adsorbate dissociation arising from a metal-substrate Auger decay. This is a further generalization of the Knotek-Feibelman model applicable for desorption in ionic systems. © 1985 The American Physical Society.
