Abstract:
A process for making an elementary particle emitting surface, comprising the steps of:a. positioning into the path of a particle beam a layer of material whose molecules are modified when exposed to said particle beam,b. directionally focusing said particle beam on said material and exposing a pattern of molecules to the beam such that the modified molecules and the unmodified molecules of said material form a pattern that comprises an indented cross-section comprising protruding portions separated by spaces, and further wherein the depths of indents in said indented cross-section is given by the relationship n.lambda.+.lambda./4, where .lambda. is the de Broglie wavelength for said elementary particles and where n is 0 or a positive integer selected such that the geometric shape of said indented cross-section causes de Broglie interference between said elementary particles,c. developing said material to remove either said modified molecules or said unmodified molecules, whereby molecules not removed by said developing form at least said protruding portions of said indented cross-section,d. transferring said pattern of said indented cross-section to a surface of a substrate whereby said indented cross-section is created on said substrate.
