摘要：

Fillingness (or 3d electron number) dependence of electronic structures in perovskite-like, titanates and vanadates is overviewed based on our recent spectroscopic studies in comparison with the case of cuprate superconductors. In common with the cuprates, though different quantitatively, changes of carrier mass and scattering rate as Well as formation of the ingap states are observed with hole-doping in the Ti3+- and V3+-based Mott insulators.
