FIG. 1.

Raman spectra of RBM (a) and GM (b) of the SWCNT rings at temperature of 100, 300, and , respectively. (c) A typical SEM image of the SWCNT rings samples.

FIG. 2.

(a) RBM frequencies shift as a function of temperature for the SWCNT rings. The lines are linear fitting results for obtaining the temperature dependence of the frequency. (b) The relation between the normalized temperature coefficient of RBM frequencies and the diameter of SWCNTs inside the rings. The dash lines are the fits with quadratic curve. (c) The comparison of the temperature-induced RBM frequency variations between the SWCNT rings and the linear SWCNTs, which have the similar diameter at room temperature.

FIG. 3.

(a)–(c) modes frequencies shift as a function of temperature for the SWCNT rings. The solid lines are the fits with second-order formula. (d) Linewidth dependence of the peaks on the temperature for the SWCNT rings. (e) The comparison of the temperature-induced GM frequency variations between the SWCNT rings and the linear SWCNTs.
