Controlled orientation of ellipsoidal fullerene C-70 in carbon nanotubes

Journal article

In single walled carbon nanotubes (SWNT), controlled orientation of ellipsoidal fullerenes C70 using density functional theory was discussed. The effect of nanotube diameter on the orientation of the ellipsoidal fullerenes was demostrated by using (10,10) nanotubes of 13.6 diameter for longitudinal orientation and (11,11) nanotubes of 14.9 diameter for transverse orientation. Raman spectroscopy and high resolution transmission electron microscopy (HRTEM) were used to examine SWNT of these diameters filled by C70 fullerenes. It was observed that all fullerenes in a given nanotube have the same transverse and longitudinal controlled orientation.
