Аннотация: The investigation of valence band structure and electronic parameters of constituent element core levels of alpha-SrB4O7 has been carried out with x-ray photoemission spectroscopy. Optical-quality crystal alpha-SrB4O7 has been grown by the Czochralski method. Detailed photoemission spectra of the element core levels have been recorПоказать полностьюded from the powder sample under excitation by nonmonochromatic Al K alpha radiation (1486.6 eV). The band structure of alpha-SrB4O7 has been calculated by ab initio methods and compared to XPS measurements. It has been found that the band structure of alpha-SrB4O7 is weakly dependent on the Sr-related states.
