  • Realization of an atomic source of metallic ions producing a surface melting by an applied electric field
    Patent number: 5274234
    Abstract: An electric field having a strength of approximately 15 V/nm is applied between a tungsten tip and a metallic substrate. Concomitantly, the tip is heated to a temperature less than the bulk melting temperature of the tungsten tip. Atoms at the surface of the tip move and form a pyramidal protrusion of nanometer scale on the tip. Topmost atoms on the protrusion are charged and form a coherent beam useful for writing atomic scale structures on the substrate.
