Abstract
A method for growing carbon nanotubes having a determined chirality includes fragmenting at least one initial carbon nanotube having a determined chirality to obtain at least two portions of carbon nanotube. Each portion has a free growth end. Atoms of carbon are supplied with an autocatalyst addition of the atoms of carbon at the free growth end of each portion of nanotube to determine an elongation or growth of the nanotube.
