We report the experimental results of quasiparticle tunneling using Bi2Sr2CaCu2O8+δ (BSCCO)-SiO-Ag planar junctions. For the {001}-oriented junctions, we have measured a well-known V-shaped gap structure expected for d-wave superconductors. For the {100}- and {110}-oriented junctions, a reproducible zero bias conductance peak (ZBCP) enhancement has been observed. The temperature dependence of the ZBCP is also presented. The ZBCP was observed below Tc. Our results are consistent with those of recent studies on the Andreev reflection between a d-wave superconductor and a normal metal.
