WebSep 1, 2007 · Abstract. The scanning tunneling microscope (STM) and the atomic force microscope (AFM), both capable of visualizing and manipulating individual atoms, are the cornerstones of nanoscience and nanotechnology today. The inventors of STM, Gerd Binnig and Heinrich Rohrer, were awarded with the Nobel Prize of physics in 1986. WebBasic principles. Scanning tunneling microscopy (STM) is an experimental technique based on the principles of quantum tunneling of electrons between two electrodes separated by a potential barrier, typically used for imaging surfaces of materials with sub-atomic resolution. It was pioneered by Gerd Binnig and Heinrich Rohrer in 1982, and was ...
