We report the experimental results of quasiparticle tunneling using Bi2Sr2CaCu2O8+δ-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.
