| Abstract: | Understanding the
nucleation and growth of carbon nanotubes at room temperature by a novel
electrochemical process using acetonitrile as the electrolyte is investigated
here. Microscopic insight into the nucleation process clearly reveals
coalescence of amorphous carbon clusters in a branched network instigated
mainly by dangling-bond induced relaxation and subsequent rearrangement of
carbon atoms through a quasi-liquid state leading to the formation of
multi-walled carbon nanotubes. Such a direct conversion of amorphous carbon
into nanotubes is not abrupt, rather driven by a slow thermodynamical process
that is inherent to the electrochemical process. |
