The binding energies of excess carriers (holes or electrons) as functions of the in-plane copper-oxygen hopping matrix element are calculated numerically by an exact diagonalization of the Emery Hamiltonian for the two-dimensional Cu408 cluster. Based on the results of the calculations, a qualitativ

To differentiate between different theories of high-To superconductivity it is useful to spell out clearly their predictions before the experiments are performed. Here we make a prediction for the change in lattice constants of electron-doped oxide superconductors under hydrostatic pressure expected
