摘要：
Following the classic strong-coupling theory of superconductivity, we find that the electron-phonon coupling with the buckling-like phonon mode makes a contribution to the d-wave order parameter in the sense of Eliashberg theory. The calculation results show that the electron-phonon interaction is partially responsible for the d-wave superconductivity in high temperature superconductors and can explain the peak-dip-hump structure and the 'kink' feature observed in the ARPES.
