摘要： A porous SOG film is formed by preparing an organic silane solution containing an organic silane, water and an alcohol, subjecting the organic silane to acid hydrolysis or alkali hydrolysis and then heat-treating the resulting reaction system in the presence of a surfactant to thus form a porous SiO2 film to use for an interlayer insulating film. Alternatively, a porous SOG film is formed by repeating the foregoing step at least one time; or by forming a hydrophobic film on the porous SiO2 film prepared by the foregoing step by the CVD or sputtering technique to thus cap the surface of the porous film; or repeating the porous film-forming and capping steps at least one time. Moreover, after the preparation of the foregoing porous SiO2 film, it is subjected to either of the oxygen plasma-treatment, electron beam-irradiation treatment and UV light-irradiation treatment to remove the unreacted OH groups remaining on the porous film and to thus form a porous SOG film. Further, the foregoing heat-treatment is carried out in the following two stages: in the first stage, the porous film is treated at a temperature capable of mainly removing the water and the alcohol through evaporation thereof; and in the second stage, the porous SiO2 film is treated at a temperature (350 to 450° C.) sufficient for covering at least the inner walls of the holes with the hydrophobic moieties of the surfactant.

摘要： A graphite nanofiber material herein provided has a cylindrical structure in which graphene sheets each having an ice-cream cone-like shape whose tip is cut off are put in layers through catalytic metal particles; or a structure in which small pieces of graphene sheets having a shape adapted for the facial shape of a catalytic metal particle are put on top of each other through the catalytic metal particles. The catalytic metal comprises Fe, Co or an alloy including at least one of these metals. The material can be used for producing an electron-emitting source, a display element, which is designed in such a manner that only a desired portion of a luminous body emits light, a negative electrode carbonaceous material for batteries and a lithium ion secondary battery. The electron-emitting source (a cold cathode ray source) has a high electron emission density and an ability of emitting electrons at a low electric field, which have never or less been attained by the carbon nanotube. The negative electrode carbonaceous material for batteries has a high quantity of doped lithium and ensures high charging and discharging efficiencies. Moreover, the lithium ion secondary battery has a sufficiently long cycle life, a fast charging ability and high charging and discharging capacities.

摘要： In forming a carbon nanotube on the surface of a substrate surface by the plasma CVD method in accordance with the prior art, since the substrate is heated by plasma, it is difficult to suitably control the temperature of substrate and thus impossible to form the carbon nanotube at a low temperature. According to the present invention there is provided a method for forming a carbon nanotube comprising steps of introducing a carbon included feedstock gas into a vacuum chamber; generating plasma so that a substrate is not exposed to plasma during a vapor phase growth of the carbon nanotube on a substrate surface; heating the substrate to a predetermined temperature by using a heater; and promoting the growth of the carbon nanotube on the substrate surface with it being contacted by the feedstock gas decomposed by plasma.
