Abstract
We found strong zero bias conductance peak enhancement in Bi2Sr2CaCu2O 8 by tunneling in the ab-plane direction. Our results are consistent w ith the recent studies on Andreev reflection between a d-wave supercon ductor and normal metal. We have also observed exotic behaviors of the conductance peak if the counter electrode is a conventional supercond uctor. If these characteristics are better understood, they can be ver y useful in studying the pairing properties in high T-c superconductor s.
