Summary
Chapter 5 discusses the Andreev reflection on a metal-superconducting interface and its effect on the tunneling conductance in d-wave superconductors. A zero-energy surface bound state is shown to exist in a d-wave pairing system. The tunneling conductance of superconducting quasiparticles in an applied bias is also derived from the tunneling Hamiltonian. The interlayer tunneling is suppressed by the anisotropic hopping integral, which leads to a modified power law with a relatively high exponent in the bias dependence of the c-axis conductance of high-Tc cuprates.
