Abstract

Scanning tunneling spectroscopy on cleaved BSCCO(2212) single crystals reveals inhomogeneities on length scales of \ensuremath∼30 \AA. While most of the surface yields spectra consistent with a d-wave superconductor, small regions show a doubly gapped structure with both gaps lacking coherence peaks and the larger gap having a size typical of the respective pseudogap for the same sample.
