Scanning tunneling microscope - Wikipedia
A scanning tunneling microscope (STM) is a type of scanning probe microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986.
Scanning Tunneling Microscope (STM): Principle ...
May 3, 2023 · The scanning tunneling microscope (STM) developed by Dr. Gerd Binnig and his colleagues in 1981 at the IBM Zurich Research Laboratory, Ruschlikon, Switzerland, is the first instrument capable of directly obtaining three-dimensional (3D) images of solid surfaces with atomic resolution.
Scanning tunneling microscope (STM) | Britannica
Scanning tunneling microscope (STM), type of microscope whose principle of operation is based on the quantum mechanical phenomenon known as tunneling, in which the wavelike properties of electrons permit them to “tunnel” beyond the surface of a solid into regions of space that are forbidden to them
Scanning Tunneling Microscopy (STM) - Oxford Instruments
Scanning Tunneling Microscopy allows researchers to map a conductive sample’s surface atom by atom with ultra-high resolution, without the use of electron beams or light, and has revealed insights into matter at the atomic level for nearly forty years.
Scanning Tunneling Microscopy - Harvard University
The scanning tunneling microscope was invented in 1982 by Binnig and Rohrer, for which they shared the 1986 Nobel Prize in Physics. The instrument consists of a sharp conducting tip which is scanned across a flat conducting sample.
Scanning Tunneling Microscope Introduction | NIST
Apr 29, 2015 · The scanning tunneling microscope (STM) is widely used in both industrial and fundamental research to obtain atomic-scale images of metal surfaces. It provides a three-dimensional profile of the surface which is very useful for characterizing surface roughness, observing surface defects, and determining the size and conformation of molecules ...
Inelastic electron tunneling spectroscopy (IETS), initially discovered in metal-insulator-metal tunneling junctions to observe vibrational frequen-cies of embedded molecules, was advanced to STM junctions, enabling the observation of vibrational states of individual molecules.
