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...
