Interactions of ions with carbon nano-structures

We review some aspects of modeling interactions of charged particles with carbon nano-structures where dynamic response of carbon valence electrons plays prominent roles. Specifically, we evaluate the effects of plasmon excitations on the image and stopping forces on fast ions and dipolar molecules channeled through carbon nanotubes, as well as the effects of single-electron excitations in graphene's π band on the image and stopping forces on slow ions grazingly scattered from a supported graphene.
