摘要: Abstract The adsorption of water on SrTiO 3 (100) has been studied by HREELS. Exposure the defect free surface to at 100K leads initially non-dissociative cation sites with development losses due OH stretching and bending modes frequencies similar those H 2 O. Further exposure results in progressive attenuation phonon substrate a loss spectrum characteristic an ice multilayer. Binding oxygen vacancy generated argon ion etching is much stronger than surface.
