Abstract

In a method of forming carbon nano-tubes, a catalytic film is formed on a substrate. The catalytic film is then transformed into preliminary catalytic particles. Thereafter, the preliminary catalytic particles are transformed into catalytic particles. Carbon nano-tubes then grow from the catalytic particles. The carbon nano-tubes have relatively high conductivity and high number density.
