Carbon nanotubes: properties and application - ScienceDirect

WebOur results illustrate the important role of doping on the magnetic properties of carbon nanotubes. Experimental studies of Δχ should take these effects into account for accurate interpretation ... Webare discussed in connection with resonant Raman spectroscopy. The effect of trigonal warping on the energy dispersion relations near the Fermi energy splits the peaks of the density of states for metallic nanotubes, and the magnitude of this effect depends on the chiral angle of the carbon nanotube.
