Abstract:
A structure comprising:a substrate for providing structural support;a lower electrically conductive region comprising a group of generally parallel highly conductive lines situated over electrically insulating material of the substrate;a porous electrically insulating layer situated over the lower conductive region;a multiplicity of electron-emissive filaments respectively situated in corresponding pores extending through the porous layer down to the lower conductive region, the lower end of each filament contacting the lower conductive region, the pores being situated at locations substantially random relative to one another; anda patterned electrically conductive gate layer situated over the porous layer, openings which respectively correspond to the filaments being provided through the gate layer at locations generally centered on the filaments such that the filaments are separated from the gate layer.
