IN-PLANE TUNNELING SPECTROSCOPY IN Bi2Sr2CaCu2O8+d-SiO-Ag PLANAR JUNCTIONS

Authors report the experimental results of quasiparticle tunneling using Bi2Sr2CaCu2O8+d-SiO-Ag planar junctions. Authors have measured the {001}-, {100}-, and {110}-oriented junctions. For the in-plane ab oriented junctions, a reproducible zero bias conductance peak has been observed. Authors analy...

Summary:Authors report the experimental results of quasiparticle tunneling using Bi2Sr2CaCu2O8+d-SiO-Ag planar junctions. Authors have measured the {001}-, {100}-, and {110}-oriented junctions. For the in-plane ab oriented junctions, a reproducible zero bias conductance peak has been observed. Authors analyzed the data by using the extended Andreev bound states model for d-wave superconductors and considered the roughness effect by averaging over in-plane directions. The experimental results are consistent with the theoretical calculations. 6 refs.
