摘要: The inelastic-tunneling model can be used to explain the linear conductance background observed in tunneling in the high-Tc oxide super conductors. Introducing a parameter into the tunneling Hamiltanian to describe the strength of on-site Coulomb repulsion, we have derived an expression for the inelastic-tunneling conductance. We further discuss what form of the spin-fluctuation propagators in the inelastic-tunneling model can produce the linear tunneling conductance which would agree well with the experimental data.
