Channeling on carbon nanotubes: a molecular dynamics approach.
We have performed classical molecular dynamics on different kinds of carbon nanotubes in order to examine their response to self-irradiation nearly parallel to the tube axis. We have found that the critical angle for channeling decays as a power law. Following the energy loss along the projectile path, we have determined the maximum range as a function of energy at the critical angle. Narrower tubes seem to be more adequate for transporting particles to longer distances.
