Abstract

The Raman spectra of the disorder-induced D-band and some other non-zone-center phonon modes of graphite and single wall carbon nanotubes are discussed using double resonance Raman theory. For two-dimensional disordered graphite, two D-band peaks and one G′-band peak are predicted. The trigonal warping effect of the constant energy contours in graphite and the van Hove singularities in the electronic and phonon energy dispersion of carbon nanotubes are of importance for discussing the line width and possible numbers of Raman peaks which come from inequivalent Raman processes.
