摘要：

The electronic structures of LaxSr1-xTiO3 (x = 0.05, 0.10) and SrTiO3-delta have been investigated by soft-X-ray emission spectroscopy. The Raman shift at the t(2g)-resonance, is a d-d transition between the incoherent and coherent bands and has an energy value of about 2.2 eV, which reflects half-intra-atomic Coulomb energy. The energy value does not change in this doping region. This is consistent with the results obtained from the effective mass and the electronic specific heat. (C) 2000 Elsevier Science B.V.
