摘要：

A wide variety of experimental conductance spectra in high-Tc superconductors can be explained by a theory of proximity-electron-tunneling spectroscopy (PETS) for d-wave superconductors. From a solution of the Bogoliubov-de Gennes equation, the conductance spectra of the PETS are proved to show gap or zero-bias peak structures depending on the axis orientation of the superconductor. The features of the calculated spectra are consistent with the experimental results of YBa2Cu3O7-δ observed by low-temperature scanning tunneling spectroscopy. © 1995 The American Physical Society.
