Stopping Power and Self-Energy for a Fast Proton in Carbon Nanotubes

Abstract

The channel effects of carbon nanotubes is studied by a fast proton in the framework of linearized hydrodynamic theory. General expressions of induced potential, the self-energy, and the stopping power are obtained for such a charged particle moving paraxially in a carbon nanotube. The influences of the damping factor and the carbon nanotube radius on the stopping power and self-energy are discussed. The results show that the velocity dependences of these quantities are strongly affected by the damping factor and the nanotube radius, the relevant results will be helpful for study of the transport of charged particles through nanotubes.
