Softening of the Radial Breathing Mode in Metallic Carbon Nanotubes

Original language description

The softening of the radial breathing mode (RBM) of metallic single walled carbon nanotubes (MSWNTs) due to electron-phonon coupling has been studied by observing the Fermi level (EF) dependence of the RBM Raman peak. In situ Raman spectra were obtainedfrom several individual MSWNTs while varying EF electrochemically. The RBM frequency of an intrinsic MSWNT is shown to be down-shifted relative to highly doped tubes by 2 cm-1. The down-shift is greatest for small diameter and small chiral angle SWNTs. Most tubes show no change in RBM linewidth. A comparison is drawn between the RBM and the G band (ALO phonon) with respect to the EF dependence of their frequencies and linewidths.
