Abstract

We have performed a systematic tight-binding analysis of the angle-resolved photoemission spectroscopy (ARPES) spectra of a series of transition-metal (TM) oxides A(TM)O3 and compared the obtained electronic structure parameters with those well established values obtained from clustermodel analyses of photoemission spectra. The values of εd εp from ARPES are found to be much larger than the values which would be expected for the limit of weak p-d hybridization, indicating that the "effective" TM 3d bands are originated from the strong hybridization with the O 2 d bands even for light TM oxides.
