    Abstract: A matrix field-emission cathode (5) comprises a monocrystalline silicon substrate (7) on which are arranged epitaxially grown pointed silicon emitters (1) which also act as ballast resistors connected in series to the emitters. In an advantageous embodiment of the proposed cathode, for a radius of curvature (r) at the emitter tip not exceeding 10 nm, the ratio of the height (h) of the emitter to the radius (r) is not less than 1000, while the ratio of height (h) to the diameter (D) at the emitter base is not less than 1. The angle .alpha. at the emitter tip does not exceed 30.degree.. The specific resistance of the emitter material is chosen so as to ensure that the resistance of each emitter will be comparable with the resistance between the cathode and the opposing electrode. The proposed cathode is used in an electronic device for displaying information which also has an anode (3) in the form of a strip (11) of phosphorescent material (10) and a conducting layer (9) whose projection onto the cathode (5) is perpendicular to the conducting paths (6) on the cathode; the anode itself acts as the control electrode.

    Abstract: A novel and advantageous cathode structure for a field emission display apparatus is disclosed. A given pixel comprises a multiplicity of spaced apart emitter bodies on a support. A given emitter body comprises diamond and/or rare earth boride, and has a relatively sharp geometrical feature that facilitates electron emission from the emitter body. By way of example, the emitter body comprises diamond bodies grown on a support, or it comprises a pre-existing diamond particle that was placed on the support. Such emitter bodies generally can be provided easily and at low cost, and typically have naturally occurring sharp geometrical features such as points and edges. We have also discovered that appropriately grown rare earth boride films of thickness 30 nm or less may substantially improve electron emission from emitter bodies, and some preferred embodiments of the invention comprise a cathode structure that comprises a thin layer of, e.g., LaB.sub.6 on the emitter bodies. Methods of making cathodes according to the invention are also disclosed.

    Abstract: A hybrid emitter exploits the electric field created by a rapidly depoled ferroelectric material. Combining the emission properties of a planar thin film diamond emitter with a ferroelectric alleviates the present technological problems associated with both types of emitters and provides a robust, extremely long life, high current density cathode of the type required by emerging microwave power generation, accelerator technology and display applications. This new hybrid emitter is easy to fabricate and not susceptible to the same failures which plague microstructure field emitter technology. Local electrode geometries and electric field are determined independently from those for optimum transport and brightness preservation. Due to the large amount of surface charge created on the ferroelectric, the emitted electrons have significant energy, thus eliminating the requirement for specialized phosphors in emissive flat-panel displays.

    Abstract: Applicants have discovered methods for making electron emitters using commercially available diamond particles treated to enhance their capability for electron emission under extremely low electric fields. Specifically, applicants have discovered that electron emitters comprising ultra-fine (5-10,000 nm) diamond particles heat-treated by a hydrogen plasma, can produce electron emission current density of at least 0.1 mA/mm.sup.2 at extremely low electric fields of 0.5-1.5 V/.mu.m. These field values are about an order of magnitude lower than exhibited by the best defective CVD diamond and almost two orders of magnitude lower than p-type semiconducting diamond. Emitters are preferably fabricated by suspending the ultra-fine diamond particles, preferably in the nanometer size range, in an aqueous solution, applying the suspension as a coating onto a conducting substrate such as n-type Si or metal, and then subjecting the coated substrate to a plasma of hydrogen, preferably at temperatures above 300.degree. C. for a period of 30 minutes or longer. The resulting emitters show excellent emission properties such as extremely low turn-on voltage, good uniformity and high current densities. It is further found that the emission characteristics remain the same even after the plasma treated diamond surface is exposed to air for several months.
