Abstract

Many 3d transition-metal oxides can be doped with electrons or holes and can be made metallic. We investigate the electronic structure of pseudo-ternary oxides in the charge-transfer and Mott-Hubbard regimes by photoemission, inverse photoemission, and x-ray absorption spectroscopy. In most cases, mid gap-states are formed upon carrier doping whereas in some cases they are not. Both electron correlation and impurity potential play an important role in the formation of mid-gap states.
