Abstract

By use of a model of highly correlated electron system, the electronic structure of the sueprconducting oxides is theoretically studied. It is shown that if holes are doped in an insulating sample, a new narrow energy band grows up inside the charge transfer gap and develops to a metallic band. The formation of the new band is quite suitable for explaining various anomalous properties of the oxides in the normal state.
