Description
Monoenergetic positrons with incident energies of less than 25 eV were employed as a nondestructive surface and near-surface sensitive probe. Positron reflectivity and the positronium emission were measured as a function of incident energy for various oxygen coverages ranging from submonolayer to 3500 A of SiO2 on Si. The characteristics of these spectra change systematically with oxidation and are in good agreement with the known development of the surface electronic structure. Different oxidation stages are identified
