Abstract: A non-thermionic field emitting device includes at least one pyramidal shaped field emitting element on one surface of an electrically conductive substrate. At least one needle-like projection is located on the tip of the pyramidal shaped field emitting element. An electron extracting electrode is mounted in parallel spaced relation to and is electrically insulated from the surface of the substrate having the field emitting element thereon. The electron extracting electrode has at least one aperture therein, the aperture being positioned substantially coaxially with a corresponding pyramidal shaped field emitting element.
