Abstract
By applying an electric field to the tip of a field-ion microscope specimen it is possible to evaporate protruding surface atoms as ions. This process, known as field evaporation,1 is thermally activated and has an activation energy dependent on the applied field strength. At a sufficiently high field strength the activation energy can be reduced to an arbitrarily low value, and so field evaooration can be made to take place at any temperature.
