Figures

FIG. 1.

(Color online) Raman spectra for the (a) RBM, (b) and bands, and (c) regions for three samples of different average lengths excited at . (d) (inset) the -band region on an expanded scale. All spectra are normalized to their -band intensities. The RBM spectra show that only one dominant SWCNT species is resonant for all samples.

FIG. 2.

(Color online) (a) as a function of , excited at different values of . (b) ratio vs for DNA-wrapped SWCNTs of different values. The ranges where S-SWCNTs and M-SWCNTs are resonant are indicated.

Image of FIG. 3.
FIG. 3.

(Color online) Comparison of the length dependence of for short SWCNT samples, excited at different , plotted in terms of the variables in Eq. (1) for nanographite (where the dotted line is for nanographite and the solid line is qualitatively for S-SWCNTs) (Ref. 5).
