SILVER-DOPED AMORPHOUS As2Se3 FILMS STUDIED BY XPS

Abstract
X-ray photoelectron spectra were measured to determine the binding energies of the core electrons in Ag films and amorphous films of As, Se As2Se3 and Ag-photo-doped-As2Se3. Auger spectra were measured to determine the kinetic energies of Ag and Ag-doped amorphous As2Se3 films. Chemical shifts by doping can be interpreted in terms of the electron transfer from Ag to As and Se ; charged defects are induced to As-Se bonds. The mechanism of the migration of Ag ions in amorphous As2Se3 is discussed.
