Scanning tunneling microscope - Wikipedia

Schematic of scanning tunneling microscopy (STM). Tunneling. Tunneling is a quantum mechanical effect. A tunneling current occurs when electrons move through a barrier that they classically shouldn’t be able to move through. In classical terms, if you don’t have enough energy to move “over” a …

Scanning Tunneling Microscopy - Nanoscience Instruments

Scanning Tunneling Microscopy. Scanning tunnelling microscopy (STM) is a proximal probe technique in which an atomically sharp tip is held sufficiently close to a surface to allow significant overlap between the tails of the wavefunctions of electronic states associated with the tip and the surface respectively.

Scanning Tunneling Microscopy - an overview ...

Scanning tunneling microscopy can be performed in two modes. In constant height mode, the tip is scanned a constant distance from the surface (typically 5–10 …
