| Abstract : |
We study the effect of Ar+ irradiation on the intermediate frequency
modes (IFM) in Raman spectra of single-wall carbon
nanotubes. We observe new features in the intermediate frequency
region from 386 to 635 cm–1 as the defect concentration
increases, whereas at the same time there is a decrease of
other IFM modes. After annealing in vacuum, the IFM modes
recover and become similar to those of the nanotubes before
irradiation. We interpret the new features in the Raman spectra
as originating from the phonon density of states that becomes
visible in the Raman process due to the presence of defects. |
