van der Waals interaction in nanotube bundles : consequences on vibrational modes
Abstract
We have developed a pair-potential approach for the evaluation of van der Waals interaction between carbon nanotubes in bundles. Starting from a continuum model, we show that the intertube modes range from 5 cm-1 to 60 cm-1. Using a non-orthogonal tight-binding approximation for describing the covalent intra-tube bonding in addition, we confirme a slight chiral dependance of the breathing mode frequency and we found that this breathing mode frequency increase by 10 % if the nanotube lie inside a bundle as compared to the isolated tube.
