Sažetak
Electron-stimulated desorption of positive and negative oxygen ions from YBa, Cu, O, surfaces has been studied as a function of electron kinetic energy in the 70- 600 eV range. It has been found that the threshold electron kinetic energy needed to induce positive oxygen ion desorption occurs at 26025 eV, whereas that associated with negative oxygen ion desorption was found to be 10025 eV. These electron kinetic energies correspond to Cu, Y, and Ba core-level binding energies. These results suggest that negative and positive oxygen ion desorption may be initiated via a primary core level ionization.
