Interactions of moving charged particles with triple-walled carbon nanotubes

摘要: We study plasmon excitations and channeling trajectories of charged particles in triple-walled carbon nanotubes (TWNTs) based on a semi-classical kinetic model combined with the Molecular Dynamics method. Numerical results show that outer inner tubes TWNT exert strong influence peak structures self-energy (or image potential) stopping power curves for ion, resulting one or two narrow peaks low speed region. In addition, radial dependencies total potential, which includes potential due to dynamic polarization electron gas reactive empirical bond order atomic interactions, are compared single-walled (SWNTs), double-walled (DWNTs) TWNTs. By comparing ion those types nanotubes, we conclude variation energy ions their distance along nanotube axis is related trajectories, exhibiting smooth helical shapes TWNTs succession sharp reflections off wall SWNTs DWNTs.
