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. [1][2][3] stm senses the surface by using an extremely sharp conducting tip that can. 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. stms have been put to use in the nano machining process, as. 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.

The scanning tunneling microscope (stm) works by scanning a very sharp metal wire tip over a surface. by bringing the tip very close to the surface, and by applying an electrical voltage to the tip or sample, we can image the surface at an extremely small scale – down to resolving individual atoms. the stm is based on several principles. 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. when a bias voltage vb is applied between tip and sample, a current will flow, and this current can be measured as.
