摘要

A production method for a tubular carbon molecule capable of arraying carbon nanotubes at finer intervals and regularly. A catalyst is disposed on a material substrate (10) consisting of a semiconductor such as silicon (Si) and containing iron (Fe) as a catalyst by utilizing melting according to modulated heat distribution (11). The heat distribution (11) is formed by diffracting energy beams (12), for example, by a diffraction lattice (13). A method of disposing a catalyst may include, for example, depositing iron in a planar or protruding form in a position matching the heat distribution (11), or further transferring it, by using it as an original, onto another substrate. Carbon nanotubes are grown using the disposed catalyst. The grown nanotubes can be used for a recording device, a field electron emission element or an FED.
