ABSTRACT

Modification of a surface of strontium titanate single crystals as pure as doped with Mn (Ni) or Nd (Sm) ions after plasma treatment was studied by combination of scanning electron microscopy and atomic force microscopy techniques. Valence shift method for characteristic X ray lines was used for study of stoichiometry violation and oxidation state of ions on the crystals surface after plasma treatment. One-and two-level ordered systems of unit crystallites sized of about 10-7 – 10-10 m were discovered on samples surface after plasma treatment with energy density of about 5 - 20 (40) J.cm-2. Oxidation state of Ti ions and stoichiometry of the surface changed essentially on background of high stability of strontium ions valence.
