Carbon nanotubes characterization by channeled fast ions spatial and angular distribution fingerprints

Abstract

In this paper we investigate possibility of carbon nanotubes characterization by differentiation in spatial and angular distribution fingerprints obtained by fast ions channeling. We analyze straight single walled carbon nanotubes (SWNTs) interacting with fast ion beams. We calculate the image potential for protons moving through the four types of SWNTs at the speeds of 3 a.u.. We calculate total potential in straight carbon nanotubes. Interaction of channelled ions with nanotube electrons we calculate by linearized, two dimensional (2D), extended two-fluid hydrodynamic model. We simulate ion beams channelling through the four types of SWNTs under calculated conditions of interaction and calculate spatial and angular distributions of channelled particles what we use as method for different SWNTs characterization.
