Abstract

A systematic resonance Raman study has been carried out on DNA-wrapped single walled carbon nanotubes (SWCNTs) of three different average lengths 〈L_tube〉 using seven different values of laser excitation energy E_laser. The dependence of the intensity ratio of the D-band and G-band Raman features (I_D/I_G) on 〈L _tube〉 indicates that nanotube length can be used as an important structural parameter for Raman characterization. By systematically varying E_laser, the ratio I_D/I_G is found to be much stronger for metallic than for semiconducting SWCNTs but appears to have the same functional dependence on E_laser and 〈L_tube〉 or crystallite size as does nanographite.
