Outline of Final Research Achievements

Ti K resonant X-ray emission spectra of SrTiO3 in quantum paraelectric phase were measured. It was that charge transfer excitation peaks were influenced by temperature decrease and UV irradiation. It can be a direct evidence that the electric dipole moment is derived from Ti off-center displacement in an oxygen otcahedon. The UV-assisted dipole moments were aligned parallel to the static electric field, as is evidenved from the additional change of the CT peak. We conclude that a local polar region formed by UV irradiation evolves under DC field application at low temperature.
