摘要：

Angle-resolved photoemission spectra of SrTiO3 (100) and (110) surfaces have been obtained. The normal-emission data are analyzed using the direct transition model and, as a result, the valence band is determined along the Delta and Sigma lines in the bulk Brillouin zone. The empirical valence-band structure is found to be consistent with the band calculations if and only if proper magnitude of the O 2p crystal-field splitting is adopted. The effect of the O 2p crystal-field splitting on the band structure is discussed.
