Abstract
We have observed Raman scattering from highly oriented pyrolytic graphite (HOPG) surfaces after irradiation with highly charged ions (HCIs) as ex situ spectroscopy. HCIs having various potential energies from 5keV for Ar16+ to 99keV for Xe50+ were normally incident onto HOPG surfaces with the same collision velocities (5×105m/s). In all spectra at fluence of 1×1011ions/cm2, disorder induced peaks (D peak) appeared around 1580cm−1 in addition to narrower peaks (G peak) which were also observed unirradiated HOPG at 1358cm−1. Relative intensities of the D peak with respect to the G peak increase gradually as increasing potential energies of the HCIs. This shows obviously the effect of potential energy deposition on structural deformation of HOPG.
