In-plane tunneling spectroscopy in Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+ delta )-SiO-Ag planar junctions

We report the experimental results of quasiparticle tunneling using Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+ delta )-SiO-Ag planar junctions. We have measured the {0 0 1}-, {1 0 0}- and {1 1 0}-oriented junctions. For the in-plane ab oriented junctions, a reproducible zero bias conductance peak has bee...

Summary:We report the experimental results of quasiparticle tunneling using Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+ delta )-SiO-Ag planar junctions. We have measured the {0 0 1}-, {1 0 0}- and {1 1 0}-oriented junctions. For the in-plane ab oriented junctions, a reproducible zero bias conductance peak has been observed. We have analyzed the data by using the extended Andreev bound states model for d-wave superconductors and have considered the roughness effect by averaging over in-plane directions. The experimental results are consistent with the theoretical calculations. copyright 2001 Elsevier Science B.V. All rights reserved.
