    • Abstract


      The metal-insulator transition induced by changing the stoichiometry (δ) in Ag2+δS has been investigated employing x-ray photoelectron and Auger electron spectroscopies. Changes in the valence band structure in x-ray photoelectron are found to reflect the conductivity behaviour in these samples. The valence bands have been examined in a novel fashion by interatomic transitions in x-ray induced Auger spectra.
