Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a patterned carbon nanotube thin film. SOLUTION: This method for manufacturing the adhered patterned carbon nanotube thin film is realized. According to the present invention, a substrate is patterned with a carbide-forming material, a carbon-dissolving material or a low melting point metal. Then, carbon nanotubes are deposited, onto the patterned substrate, but have relatively, poor adhesion to the substrate material or the pattern-forming materials. The substrate is subsequently annealed typically in vacuo at a temperature dependent on the particular patterning material, such as a carbide-forming temperature, a carbon-dissolution temperature or a low melting point metal-melting temperature. By the annealing, an adhesive nanotube thin film is formed over the patterned regions, while the nanotubes deposited on the non-patterned regions are easily removed, for example, by blowing, rubbing, brushing or ultrasonication in a solvent such as methanol.

Abstract: PROBLEM TO BE SOLVED: To easily assemble a nano-tube to a device by forming an adhesive carbon nano-tube film on a substrate. SOLUTION: In the manufacture of a flat panel display using a thin film nanotube electric field emitter, the display is provided with a cathode 41 having plural nano-tube emitters 47 and an anode 45 arranged separately from the emitters in vacuum sealing. A fluorescent layer 44 is provided on an anode conductor 49 formed on a transparent insulation substrate 46. A perforated electrically conductive gate layer 43 is provided between the cathode 41 and the anode 45 in the vicinity of the emitters 47 with an interval therebetween. When a space between the anode 45 and the cathode 41 is evacuated, and the voltage is applied, the electric field emitted electrons from the emitters 47 are accelerated by the electrically conductive gate layer 43, and moved toward the anode conductor 49. The electrons collide with the fluorescent layer 44 arranged between the emitters 47 and the anode 45 to generate the display image.

Abstract: 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.

Abstract: The invention provides improved devices containing adherent carbon nanotube films, in particular electron field emitter structures containing such films. Previously, attaining even moderate adherence of powdery or mat-like nanotubes to a substrate was difficult, because of the perfect fullerene structure of nanotubes, which tend to exhibit no dangling bonds or defect sites where chemical bonding to the substrate is able to occur. The invention overcomes these problems, and provides a strongly adherent nanotube film, by a variety of fabrication processes.
