Do Carbon Nanotubes Spin When Bundled?

Abstract

Using ab initio and parametrized techniques, we determine the equilibrium structure of an ordered “bundle” of (10,10) carbon nanotubes. Because of small intertube interaction and lattice frustration, we predict a very soft libration mode to occur at v ≈ 12 cm−1. This mode is predicted to disappear above the orientational melting temperature which marks the onset of free tube rotations about their axis. We discuss the effect of the weak intertube coupling and orientational disorder on the electronic structure near the Fermi level.

22. Rather than using a fixed cutoff distance in our parametrized scheme, which would cause artifacts in the energy due to a changing neighbor map during tube rotations, we obtained the potential energy surface by carefully integrating over energy differences due to small rotations, during which the neighbor map was kept fired.
