WebbWe report topographic scanning tunnelling microscopy measurements on the (001) and (100) surfaces of YBa2Cu3O7‐δ single crystals, together with a theoretical basis by which the surface structures can be understood. We show that it is possible to obtain reproducible topographic data on a clean (001) and (100) surface in air. The results … WebbScanning tunneling microscopy (STM) is a tool that profoundly shaped nanoscience and nano- technology. Since its invention by Rohrer and Binnig [1, 2, 3], for which they were awarded the 1986 Nobel prize in Physics, STM experienced revolutionary developments allowing to see for the first time nanostructures at the atomic scale.
