Abstract

Low temperature STM/STS observations have been carried out on cleaved BSCCO crystal surfaces. We have succeeded in detection of a special layer, probably a CuO₂ or Ca layer exposed on the surface. The STS spectrum which was reproducibly observed on this special site shows a considerably anisotropic but distinct superconducting gap structure with a definite and flat gap bottom region. This gap structure shows significantly different characteristic from another gap structure observed on the BiO layer, which shows a rounded shape at the gap bottom region without any indication of a finite gap state.
