We have considered a two-band Hubbard model having interlaced Cu-Sd(x 2 \_y2) and O-2p(x,y) orbitals representing the Cue 2 square planes. Simple CuQ~-cluster calculation suggests that the additional holes created by doping stay mainly on oxygen. Motibn of an oxygen hole interlacing with the antife
We study thermodynamic properties of a high-Tc superconductor described by the hole-pairing model. Our earlier formulation is generalized by including effects ofintersite Coulomb repulsion between holes and an expression for the gap function is derived. The temperature dependence of the gap function
