Base-growth mechanism of double-walled carbon nanotube in chemical vapor deposition

In this paper, a novel theoretical model based on phonon vibrations of the system is presented to explain base-growth of double-walled carbon nanotubes in chemical vapor deposition. In this regard, influence of interwall interaction and chirality on growth is also studied. Results of the presented theory are in good agreement with reported experimental results.

► Base-growth mechanism of DWCNT is presented.
► DWCNTs with larger diameter grow less.
► Zigzag DWCNTs grow less than armchair DWCNTs.
