Abstract
An apparatus for synthesizing highly oriented, aligned carbon nanotubes from an alcohol includes a liquid tank for retaining an alcohol; a water cooling device for cooling the liquid tank from its outside; a condensing device for cooling and condensing vapor from the alcohol; a substrate holding device having an electrode for passing an electric current through the substrate in the alcohol; an inert gas inlet for removing air; a tank sealing device to prevent the alcohol becoming gaseous in phase; and a temperature measuring device, wherein the Si substrate with a buildup thereon of the thin film or insular particles is heated by electric current to a temperature, thereby providing a temperature gradient from the Si substrate surface toward the alcohol, wherein said thin film or insular particles is a catalyst for synthesizing carbon nanotubes, and the carbon nanotubes are synthesized.
