Summary: | The adsorption of water on SrTi0 3 (100) has been studied by HREELS. Exposure of the defect free surface to water at 100K leads initially to non-dissociative adsorption on surface cation sites with development of losses due to 0-H stretching and bending modes at frequencies similar to those of free H 2O Further exposure results in progressive attenuation of the surface phonon losses of the substrate with development of a loss spectrum characteristic of an ice multilayer. Binding of water in oxygen vacancy sites generated by argon ion etching is much stronger than to the defect free surface. © 1983 Elsevier Scientific Publishing Company. |
