Electronic structure and dynamics of ordered clusters with ME or RE ions on oxide surface

► External influence and variation of technology induce changes in valence of nl ions in compounds. ► Wave function of cluster presented as anti-symmetrical set of ions wave functions. ► The main equation describes the self-consistent field depending on state of all electrons of cluster. ► Level scheme of Cr4+ ions in octo- and tetra-site corresponds to doped oxides spectra after treatment. ► Plasma treatment effects in appearance of systems of unit crystallites with size of about 10−6-10−9 m.
