ABSTRACT:
According to a method of manufacturing carbon nanotubes, minute concavities and convexities are formed at a surface of a substrate, a catalyst metal layer having a predetermined film thickness is formed on the surface having the concavities and convexities, the substrate is subject to a heat treatment at a predetermined temperature to change the catalyst metal layer into a plurality of isolated fine particles. The catalyst metal fine particles have a uniform particle diameter and uniform distribution. Then, the substrate supporting the plurality of fine particles is placed in a carbon-containing gas atmosphere to grow carbon nanotubes on the catalyst metal fine particles by a CVD method using the carbon-containing gas. The carbon nanotubes can be formed to have a desired diameter and a desired shell number with superior reproducibility.
