      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.

    • Ionic conduction in dispersed solid-electrolytes

      More Details Abstract Fulltext PDF

      In recent years, considerable interest has been focussed on developing solid electrolytes with high ionic conductivities. One of the latest techniques is the dispersion of a non-conducting and chemically non-interacting phase in the solid electrolyte. These electrolytes have been referred to as dispersed solid-electrolyte systems. The present paper briefly reviews the characteristic features of dispersed solid-electrolytes and the mode of ion conduction in these systems.
