Abstract
Tunneling images of an Y1Ba2Cu3O7−x high Tc superconductor have been obtained in air. Slow scanning images show the roughness of surface in agreement with scanning electron microscope observations. Fast scanning pictures show the periodic structure with dimensions comparable to those of the bulk layered perovskite unit cell of the material.Keywords
