    Abstract: PROBLEM TO BE SOLVED: To provide adhesiveness and a stable structure, and to relatively facilitate manufacture, by projecting at least a part of nano-tubes from the surface of a composite material and setting average projection two times higher than the average diameter of the nano-tube in the composite material. SOLUTION: Carbon nano-tubes 10 and conductive metal powder 12 are prepared, and are actually mixed as uniform as possible, and an obtained composite material is pressed into a green compact 14. An ingot is cut in parallel with an intended emitter surface, or a composite material layer is polished and removed from an ingot surface to expose many nano-tubes 16. A metal layer is removed with edges from the surface of the cut ingot 17 to provide many projecting nano-tubes 16. In this case, length of the projections is two times longer than an average diameter of the nano-tubes, and more preferably 10 times longer than the average diameter.

    Abstract: An improved process for fabricating nanotube field emitter structures is provided, in which the nanotubes protrude from a supporting base material to improve emission properties. The resulting emitter structure are useful in a variety of devices, including microwave vacuum tube devices and flat-panel, field-emission displays. To attain the protruding nanotube emitter structure, according to one embodiment of the invention, nanotubes and metal particles are mixed and consolidated into a compact, and the compact is then sectioned to expose a substantial number of nanotube ends. A layer of the metal is selectively etched from the sectioned surface, leaving the exposed nanotubes protruding from the surface. The extent of protrusion is at least twice the average diameter of the nanotubes, advantageously at least ten times the average diameter of the nanotubes.
