    摘要: A fine spherical particle formed of diamond as a core and having carbon nano-materials radially grown therefrom is disclosed, which exhibits the appearance of a Marimo (Cladophora sauteri) particle. Fine diamond catalytic particles 2 whose surfaces are oxidized and treated to carry a transition metal catalyst are floated and stirred in a gas phase of hydrocarbon while being heated at a selected temperature to bring about a catalytic reaction which synthesizes carbon nano-materials and to grow them on the surface of said oxidized fine diamond particle. Nano fibers or filaments 32 of a nano size are grown from the fine diamond catalytic particle 31 as a core to form cladophora-form carbon. The carbon nano-materials if the supported transition metal is Ni or Co become carbon nano-tubes and if it is Pd become coin stacked carbon nano-graphite.

    摘要: A novel carbon nanotube (64) is featured in that it has the highest Raman scattering intensity in the vicinity of 1580 cm−1 in its Raman spectrum. Carbon nanotubes can be grown on and from the catalytic fine particles (63) which consist of ultra-fine particles of cobalt oxide catalyst onto a substrate comprising a conductive substrate (62) and fine particles (63) of catalyst formed on a surface thereof. An electron emission device (60) so configured as to emit electrons by applying a voltage to apical ends (64a) of such carbon nanotubes (64) can be reduced in driving voltage and can achieve a current such as to emit a fluorescent material on the market for low-velocity electron beams. The electron emission device (60) needs no gate and can thus simplify the structure and reduce the cost of a surface light-emitting device for which the element is used. The carbon material remains unoxidized even in a low vacuum and thus allows realizing a light emitting device that can be paneled more easily, and is longer in operating life than those using a conventional electron emission device.

    摘要: A substrate is polished and made an inclined substrate, which is exposed to a hydrogen plasma and is thereby smoothened. The substrate is then heated controlledly until it surface temperature reaches 830° C. Meanwhile, a gas mixture of 1% methane, 50 ppm hydrogen sulfide and hydrogen is introduced in a tubular reaction vessel to flow therethrough at 200 ml/min, where microwave plasma is excited to cause n-type semiconductor diamond to epitaxially grow on the substrate. An ion doped n-type semiconductor is thus formed that has a single donor level of an activation energy at 0.38 eV and is high in mobility and of high quality.
