TL;DR: The first use of a vacuum tunneling microscope to spatially resolve changes in the electronic structure of a superconducting surface was reported in this article, where the authors observed reproducible changes in this structure as the tip is laterally scanned between two locations on the surface separated by 220 A.
Abstract: We report what we believe is the first use of a vacuum tunneling microscope to spatially resolve changes in the electronic structure of a superconducting surface. The exponential dependence of the tunneling resistance on gap spacing is demonstrated at 300, 77, and 15 K. Current‐voltage characteristics at low temperature show a structure that can be attributed to the superconducting gap of the Nb3Sn sample studied. We observe reproducible changes in this structure as the tip is laterally scanned between two locations on the surface separated by 220 A.
