Abstract

Single wall carbon nanotube (SWNT) doped by alkali-metals are investigated by Raman scattering. For saturation-doped compounds, the most striking intrinsic features are two low-frequency peaks assigned to modes involving both radial motions of tubes and alkali-atoms vibrations. On the other hand, the evolution of the Raman spectra with doping was studied in-situ. Two different stable phases are identified and associated to distinct organizations of the tubes and of the alkali-atoms.
