    Abstract: An electron field emission device is provided by placing a substrate in a reactor, heating the substrate and supplying a mixture of hydrogen and a carbon-containing gas at a concentration of about 8 to 13 percent to the reactor while supplying energy to the mixture of gases near the substrate for a time to grow a first layer of carbon-based material to a thickness greater than about 0.5 micrometers, subsequently reducing the concentration of the carbon-containing gas and continuing to grow a second layer of carbon-based material, the second layer being much thicker than the first layer. The substrate is subsequently removed from the first layer and an electrode is applied to the second layer. The surface of the substrate may be patterned before growth of the first layer to produce a patterned surface on the field emission device. The device is free-standing and can be used as a cold cathode in a variety of electronic devices such as cathode ray tubes, amplifiers and traveling wave tubes.

    Abstract: A field emission display apparatus includes a plurality of emitters formed on a substrate. Each of the emitters includes a titanium silicide nitride outer layer so that the emitters are less susceptible to degradation. A dielectric layer is formed on the substrate and the emitters, and an opening is formed in the dielectric layer surrounding each of the emitters. A conductive extraction grid is formed on the dielectric layer substantially in a plane defined by the emitters, and includes an opening surrounding each of the emitters. A cathodoluminescent faceplate having a planar surface is disposed parallel to the substrate.

    Abstract: A method for fabricating field emitters from a conductive or semiconductive substrate. A layer of low work function material may be formed on the substrate. Emission tips that include such a low work function material may have improved performance. An etch mask appropriate for forming emission tips is patterned at desired locations over the substrate and any low work function material thereover. An anisotropic etch of at least the substrate is conducted to form vertical columns therefrom. A sacrificial layer may then be formed over the vertical columns. A facet etch of each vertical column forms an emission tip of the desired shape. If a sacrificial layer was formed over the vertical columns prior to formation of emission tips therefrom, the remaining material of the sacrificial layer may be utilized to facilitate the removal of any redeposition materials formed during the facet etch.

    Abstract: A high performance novel electron emitter material for use in field emission devices is disclosed. The high performance electron emitter material of the invention may comprise a high Cr and SiO mixture. This material may be formed into high aspect ratio, low work function tips which maintain their shape, thus minimizing flash over risks and electron scattering problems, while at the same time permitting a high level of fabrication process flexibility, and minimizing film stresses. One or more impurities which are conductive oxides or will form conductive oxides may be added to the Cr--SiO composition so that a net low work function emitter may be maintained under oxidation. A class of semi-conductive and conductive metal oxides comprises another embodiment of the invention. These materials include oxides of Cr, Mo, Ni, Fe, and Sc, which have current emitting properties desirable for applications where improved electron emission infirmity is desired among emitters within a pixel. Emission from these more resistive emitter tip materials may be optionally enhanced with the addition of low work function impurities such as alkali metals enabling more stable devices while still permitting low turn-on voltages. Methods of making the emitter are also disclosed.
