Characterization of hydrogen species on metal-oxide surfaces by electron-stimulated desorption: TiO/sub 2/ and SrTiO/sub 3/*

PDF Version Also Available for Download.

Description

The hydrogen species on TiO/sub 2/ and SrTiO/sub 3/ have been characterized using the site specificity of electron-excited Auger Stimulated Desorption (ASD). Hydrogen is found to be bonded to surface Ti's in hydride-type bonds, to subsurface or bridgebonded O's in a hydroxyl-like bond, or be part of a surface hydroxyl. On SrTiO/sub 3/ the Ti-H and surface OH species are also found plus a high density of Sr-H and very little Sr-OH bonding. The general features of ASD, both electron- and photon-excited, are discussed.
