Non lithographic technique for the production of large area high density gridded field emission sources
We report a novel method for the production of high density arrays of gridded microtip field emission electron sources. The microporous structure of Al2O3, formed by anodization of Aluminum, is exploited to provide a high density (109 sites cm-2) of sites for emitter fabrication without the need for...

description | We report a novel method for the production of high density arrays of gridded microtip field emission electron sources. The microporous structure of Al2O3, formed by anodization of Aluminum, is exploited to provide a high density (109 sites cm-2) of sites for emitter fabrication without the need for individual lithographic patterning of each emitter. The small size of the resultant emitters enables operation with only moderate extraction voltage (20-50 V). Tests of groups of ≈400,000 emitters have demonstrated emission current densities suitable for display applications. |
