One-dimensional nanostructures grown inside carbon nanotubes upon vapor deposition: A growth kinetic approach

Aiming at controlling the growth of one-dimensional nanostructures inside carbon nanotubes, a growth kinetic approach was performed, with respect to the effect of nanosize induced additional pressure on growing kinetics, to theoretically elucidate the growth of one-dimensional nanostructures inside carbon nanotubes upon vapor deposition. Our analysis showed that the growth rate of one-dimensional nanostructures would go much higher once nuclei formed inside carbon nanotubes, due to the effect of surface tension induced by the nanosize curvature of carbon nanotubes. The results based on the proposed model are in good agreement with experimental data for nanowires grown inside carbon nanotubes upon vapor deposition.
