scanning tunneling microscopescanning tunneling microscope
a type of electron microscope capable of generating a three-dimensional image showing individual atoms: it consists of a moving electrode that scans an object by means of a line of tunneling electrons that flow between the tip of the electrode and the object
Origin of scanning tunneling microscopesee tunnel (intransitive verb)
