Abstract

Carbon atoms are fed to a catalytic metal particlehaving a atomic arrangement of triangular lattices in a round (or partly round) of a side wall, and a graphen sheethaving a six-membered structure reflecting the atomic arrangement of the triangular lattices is consecutively formed by the metal catalyst, whereby a tubular structure of the carbon atoms is formed. Thus, the chirality of the tubular structure can be controlled by the growth direction of the graphen sheet with respect to the direction of the triangular lattices, and the diameter of the tubular structure can be controlled by the size of the catalytic metal particle.
