Resumen

We found strong zero bias conductance peak enhancement in Bi₂Sr₂CaCu²O₈/Pb by tunneling in the ab-plane direction. Our results are consistent with the recent studies on Andreev reflection between a d-wave superconductor and normal metal. We have also observed exotic behaviors of the conductance peak if the counter electrode is a conventional superconductor. If these characteristics are better understood, they can be very useful in studying the pairing properties in high T_c superconductors.
