  Field ion microscope - Wikipedia, the free encyclopedia
The field ion microscope is a type of microscope that can be used to image the arrangement of atoms at the surface of a sharp metal tip.
In FIM, a sharp metal tip is produced and placed in a vacuum chamber, which is backfilled with an imaging gas such as helium or neon.
Gas atoms adsorbed on the tip are ionized by the strong electric field in the vicinity of the tip (thus, "field ionization"), becoming positively charged and being repelled from the tip.
