The scanning tunneling microscope (STM) was developed at IBM in the 1980s by Gerd Binnig and Heinrich Rohrer, however no introduction to scanning probe microscopy would be complete without mentioning the contribution of Edward Hutchinson (Hutchie) Synge STM can form an image of individual atoms on a metal, semiconductor or other conductive sample surface by scanning the tip of a needle over the surface at a height of only a few atomic diameters, so that tunnel current occurs between the tip and the sample The Scanning Tunneling Microscope allows to measure the topography of metals, the position of their atoms, and the electron characteristics in the metal. A metallic tip is positioned very close to the surface of the metal. A voltage applied between the tip and the surface creates a tunneling current Scanning tunneling microscope (STM) is a powerful technique for viewing surfaces at the atomic level.
