Surface nanostructures in oxides doped with Me/RE ions

Author(s): N.A.Kulagin

The results of studying experimental and theoretical results on spectral properties of selected oxides as pure as doped withMe/RE ions discussed this paper. Experimental data resulting from investigation of radiation induced defects in sapphire and strontium titanate over ã- or plasma flow. Ordered and quasi-ordered nano- and sub-nanostructures were discovered on surface of the oxides over plasma flow and performed using high resolution SEM and AFM techniques. Registered ion’s X ray line shift shows change in the oxidation state in the host and impurity ions. XRD data were calculated for crystal’s crystalline lattice. Ab initio simulation of cluster electronic structure and ions energy level’s scheme was taken into account for interpretation.
