摘要： A gridded microwave tube contains a cold cathode, an anode, and a grid located between the anode and cathode. In one embodiment, the cold cathode has a refractory metal substrate (30,50,60,70,80,90) and carbon nanotube emitters (32,42,53,62,73), the emitters (32,42,53,62,73) having a diameter of 1 to 300nm and a length of 0.05 to 100µm. The grid-cathode spacing is 1 to 100µm, the grid (34,43,54,63,74) contains apertures having a maximum dimension of 0.5 to 100µm, and the grid thickness is 0.1 to 50µm. Emission from the cathode directly onto the grid material itself, which undesirably heats the grid, is reduced by either (a) the presence of a shadow mask (33) between the grid (34) and the emitters (32) or (b) selective formation of the emitters (42,53,62,73) on the surface of the substrate (50,60,70,80,90). The microwave tube operates at a frequency of greater than 0.5GHz, advantageously greater than 2GHz.

摘要： An improved process for fabricating emitter structures from nanowires, wherein the nanowires are coated with a magnetic material to allow useful alignment of the wires in the emitter array, and techniques are utilized to provide desirable protrusion of the aligned nanowires in the final structure. In one embodiment, nanowires at least partially coated by a magnetic material are provided, the nanowires having an average length of about 0.1 µm to about 10,000 µm. The nanowires are mixed in a liquid medium, and a magnetic field is applied to align the nanowires. The liquid medium is provided with a precursor material capable of consolidation into a solid matrix, e.g., conductive particles or a metal salt, the matrix securing the nanowires in an aligned orientation. A portion of the aligned nanowires are exposed, e.g., by etching a surface portion of the matrix material, to provide desirable nanowire tip protrusion.

摘要： This invention is predicated on applicants' discovery that a highly oriented nanoconductor structure alone does not guarantee efficient field emission. To the contrary, the conventional densely populated, highly oriented structures actually yield relatively poor field emission characteristics. Applicants have determined that the individual nanoconductors in conventional assemblies are so closely spaced that they shield each other from effective field concentration at the ends, thus diminishing the driving force for efficient electron emission.
In accordance with the invention, an improved field emitting nanoconductors assembly (a "low density nanoconductor assembly") comprises an array of nanoconductors which are highly aligned but spaced from each other an average distance of at least 10% of the average height of the nanoconductors and preferably 50% of the average height. In this way, the field strength at the ends will be at least 50% of the maximal field concentration possible. Several ways of making the optimally low density assemblies are described along with several devices employing the assemblies.

摘要： 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.

摘要： Ion beam deposition, using a carbon- and fluorine-containing source or sources, is used to form a fluorinated diamond-like carbon layer in a device, the FDLC layer exhibiting a dielectric constant of 3.0 or less along with a thermal stability of at least 400°C. During the ion beam deposition, due to the unique nature of carbon chemistry, the carbon atoms combine at the substrate surface to form all possible combinations of sp 1 , sp 2 and sp 3 bonds. However, ion beam etching occurs along with deposition, such that atoms of the weaker carbon structures - carbyne and graphite - are removed preferentially. This leads to a buildup of a diamond-like, sp 3 -bonded structure with fluorine atoms, it is believed, substituted for some carbon atoms within the structure, this structure providing the desirable properties of the layer.

The buffer layer may be a solid solution or a multiphase alloy. A method of making the cathode by depositing a buffer between a surface of the substrate and an emissive layer, where the deposited buffer alters, randomizes, miniaturizes, and/or isolates the grain structure at a surface of the substrate to reduce the grain size, randomize crystal orientation and reduce the rate of crystal growth.

摘要： The process of the invention is capable of providing conformably-aligned nanotubes perpendicular to the local surface of a flat or non-flat substrate, with an average deviation less than 15°, while also allowing control over the nanotube diameter, length, and location. In particular, the invention uses a high frequency plasma enhanced chemical vapor deposition (PECVD), advantageously with an acetylene-ammonia chemistry, to provide such results, typically with cobalt as a catalyst metal.

摘要： A method for fabricating adherent, patterned carbon nanotube films is provided. According to the invention, a substrate is patterned with a carbide-forming material, a carbon-dissolving material, or a low melting point metal. Carbon nanotubes are then deposited onto the patterned substrate, but have relatively poor adhesion to either the substrate material or the patterned material. The substrate is then annealed, typically in vacuum, at a temperature dependent on the particular patterning material, e.g., a temperature at which carbide formation occurs, at which carbon dissolution occurs, or at which the low melting point metal melts. The annealing thereby provides an adherent nanotube film over the patterned areas, while the nanotubes deposited onto the non-patterned areas are easily removed, e.g., by blowing, rubbing, brushing and/or ultrasonication in a solvent such as methanol.
