Abstract
The electronic structure of -type has been studied by photoemission spectroscopy (PES). Comparing with the PES of -type the Fermi level of type is lower by about 0.7 eV and a prominent feature of Ti character within the band gap, which is formed in the -type cannot be found in -type It is suggested that the band structure of -type follows the rigid-band model. The resonant photoemission study shows that the Ti partial density of states in the valence band of -type is much larger than that of -type Furthermore, it is also found that the satellite intensities of several core lines in -type are stronger than those in -type These facts suggest that the hybridization effect between the Ti and O states becomes stronger in -type
