Abstract : A field emitter structure is disclosed which comprises: a substrate selected from the group consisting of a semi-insulating substrate and an insulating substrate, the substrate having first and second surfaces and at least one hole therethrough; a first conducting layer disposed on the first surface of the substrate and having at least one aperture aligned with an associated at least one hole in the substrate, the at least one aperture of the first conducting layer comprising an extraction electrode, and a second conducting layer disposed on the second surface and projecting into the at least one hole in the substrate and into the at least one associated aperture of the first conducting layer and forming at least one associated apex inside the at least one hole, the at least one associated apex comprising an associated electron field emitter. In a second embodiment of the invention, a conducting substrate is substituted for the insulating or semi-insulating substrate, a first insulating layer is disposed between the first surface of the conducting substrate and the first conducting layer, and the second conducting layer disposed on the second surface also projects through at least one associated aperture of the first insulating layer.
