内容記述 | Electronic states in the two-band Hubbard model with infinite dimensions are investigated by using the exact diagonalization method. In the half-filled case, the phase boundary separating the metallic and the insulating regimes is obtained a function of the on-site repulsive interaction U and the charge-transfer energy Δ. TheMott metal–insulator transition of obtained when U is varied for the case with U<Δ(Mott-Hubbard type), while it is observed when Δ is varied for the case with U>Δ(charge-transfer type). In the doped case, on-site paring susceptibility is calculated at finite temperature and the critical temperature of the superconductivity is found in a charge-transfer type while not in a Mott–Hubbard type. | |||||
