Theory of the scanning tunneling microscope
WebbSynchrotron X-ray scanning tunneling microscopy ( SX-STM) is an imaging technique combining the best of two worlds: the exceptional chemical, magnetic, and structural sensitivity of X-rays combined with the unparalleled ability of scanning probe microscopy to resolve and manipulate surfaces down to single atoms. WebbWe report topographic scanning tunnelling microscopy measurements on the (001) and (100) surfaces of YBa2Cu3O7‐δ single crystals, together with a theoretical basis by …
