Abstract: The present invention relates to a method for manufacturing a transition metal-carbon nanotube hybrid material using nitrogen as a medium. The present invention is characterized in that nitrogen-added carbon nanotube is grown in the presence of metal catalyst particles by reacting an hydrocarbon gas with a nitrogen gas by a chemical vapor deposition (CVD) and a transition metal-carbon nanotube hybrid material where a transition metal is uniformly attached to the entire carbon nanotube structure in which nitrogen with a great chemical reactivity is added as heterogeneous elements is chemically manufactured. Therefore, the present invention does not use an acid treatment required to attach transition-metal atoms to the carbon-nanotube, a surface treating process using a surfactant and the like and an inhibitor for preventing the coagulation of the transition metal so that a simplification of the process is obtained and the method is an environment-friendly method. The transition metal-carbon nanotube hybrid material manufactured by the above can be applied variously as a hydrogen storage material, a catalyst material, an electric field emission device and an electrode material.

Abstract: A carbon-nano tube (CNT) structure comprises a substrate and a plurality of CNTs, each CNT comprising a plurality of first CNTs grown perpendicular to the substrate and a plurality of second CNTs grown on sidewalls of the first CNTs. A method of manufacturing CNTs includes growing first CNTs on a substrate on which a catalyst material layer is formed, and growing second CNTs on surfaces of the first CNTs from a catalyst material on surfaces of the first CNTs. The second CNTs grown on the sidewalls of the first CNTs emit electrons at a low voltage. In addition, the CNT structure exhibits high electron emission current due to the second CNTs being used as electron emission sources, and exhibits uniform field emission due to the uniform diameter of the first CNTs. A display device incorporates the above-described structure.

Abstract: Hybrid composites including carbon nanotubes and a carbide-derived carbon material, electron emitters including the hybrid composites, methods of preparing the electron emitters, and electron emission devices including the electron emitters are provided. Specifically, a hybrid composite includes at least one carbon nanotube and a carbide-derived carbon material. The carbide-derived carbon material is prepared by thermochemically reacting a carbide compound with a halogen-containing gas to extract substantially all of the elements except for the carbon in the carbide compound. Since the carbon nanotubes and the carbide-derived carbon material are hybridized and composited, a screen effect that may occur when large amounts of carbon nanotubes are used can be prevented, and an electron emitter including the hybrid composite has excellent electron emission capabilities, excellent uniformity, and a long lifetime.

Abstract: The present invention relates to a method for forming metal-silicide catalyst nanoparticles with controllable diameter. The method according to embodiments of the invention leads to the formation of ‘active’ metal-suicide catalyst nanoparticles, with which is meant that they are suitable to be used as a catalyst in carbon nanotube growth. The nano-particles are formed on the surface of a substrate or in case the substrate is a porous substrate within the surface of the inner pores of a substrate. The metal-silicide nanoparticles can be Co-silicide, Ni-silicide or Fe-silicide particles. The present invention relates also to a method to form carbon nanotubes (CNT) on metal-silicide nanoparticles, the metal-silicide containing particles hereby acting as catalyst during the growth process, e.g. during the chemical vapour deposition (CVD) process. Starting from very defined metal-containing nanoparticles as catalysts, the diameter of grown CNT can be well controlled and a homogeneous set of CNT will be obtained.

A catalyst is arranged on a material substrate (10) made of a semiconductor such as silicon (Si) and including iron (Fe) as a catalyst through the use of melting according to a modulated heat distribution (11). The heat distribution (11) is formed, for example, through diffracting an energy beam (12) by a diffraction grating (13). As a method of arranging the catalyst, for example, iron may be deposited in a planar shape or a projection shape in a position corresponding to the heat distribution (11), or the deposited iron may be used as a master to be transferred to another substrate. A carbon nanotube is grown through the use of the arranged catalyst. The grown carbon nanotube can be used as a recording apparatus, a field electron emission device, an FED or the like.
