microscopy Definition

the use of or investigation with a microscope

an instrument used for mapping the atomic-scale topography of a surface by means of the repulsive electronic forces between the surface and the tip of a microscope probe moving above the surface —abbreviation AFM

an electron-optical instrument in which a beam of electrons is used to produce an enlarged image of a minute object

an electron microscope in which a beam of focused electrons moves across the object with the secondary electrons produced by the object and the electrons scattered by the object being collected to form a three-dimensional image on a display screen —called also scanning microscope

a microscope that makes use of the phenomenon of tunneling electrons to map the positions of individual atoms in a surface or to move atoms around on a surface
