Description

By employing molecular dynamics simulations, we study thermal relaxation in two types of nanoclusters, a cubelike stack of identical carbon nanotubes and a nanocube of fullereneC60 molecules. We calculate relaxation time and coefficient of thermal conductivity and reveal that the C60nanocluster demonstrates anomalously slow thermal relaxation due to the excitation of long-lived internal localized oscillatory modes. This suggests that such nanoclusters would be the most efficient for...[Show more]

We calculate relaxation time and coefficient of thermal conductivity and reveal that the C60nanocluster demonstrates anomalously slow thermal relaxation due to the excitation of long-lived internal localized oscillatory modes. This suggests that such nanoclusters would be the most efficient for photophoretic manipulation of fullerenes.
