Abstract:
A structure comprising:a sub-structure comprising an electrically non-insulating emitter layer divided into mutually insulated emitter lines; a pluality of electron etters situated over said emitter lines, each emitter comprising electrically non-insulating material; an electrically non-insulating gate layer having an upper surface spaced largely above said electron emitters, said gate layer having a plurality of gate holes each corresponding to one of said electron emitters, said gate layer being divided into mutually insulated gate lines; and a carbon-containing layer coated over each of said electron emitters and directly on at least part of said gate layer, said carbon-containing layer comprising tetrahedral amorphous carbon, at least part of said carbon-containing layer along and above said gate layer being exposed to open space external to said structure.
