Li and F intercalation to a nano-graphite cluster whose diameter is about 20 Å is discussed theoretically. Electronic structure of the nano-graphite cluster is calculated with the ionic impurities on the cluster. We also reporte the calculated result of Raman intensity for single wall carbon nanotubes.
Key words: nano-graphite, cluster calculation, mopac93, Gaussian94, carbon nanotube, Raman intensity
