X-ray photoelectron spectroscopy (XPS or ESCA), is an analytical technique that depends upon the measurement of the energies of photoelectrons that are emitted from atoms when they are irradiated by soft X-ray photons (1 – 2 keV). When used to study solids, XPS analysis has a number of...
A review of an X-Ray Photoelectron Spectroscopy (XPS) analysis of oxide solid solutions is presented, aimed at the study of surface composition. The systems NiO-MgO, CoO-MgO, ZnO-MgO are discussed. It is shown that a small depletion of Ni and Co is present, whilst Zn is enriched. The...
