Abstract
Using as a model the Hubbard Hamiltonian we determine various basic properties of electron-doped cuprate superconductors like Nd2−xCexCuO4 and Pr2−xCexCuO4 for a spin-fluctuation-induced pairing mechanism. Most importantly we find a narrow range of superconductivity and, similar to hole-doped cuprates dx2−y2, symmetry for the superconducting order parameter. The superconducting transition temperatures Tc(x) for various electron doping concentrations x are calculated to be much smaller than for hole-doped cuprates due to the different energy dispersion and a flat band well below the Fermi level. Lattice disorder may sensitively distort the symmetry dx2−y2 via electron-phonon interaction.
