Abstract
Temperature-dependence of resonant Raman scattering in double-wall carbon nanotubes was investigated. It was found that differential radial breathing mode (RBM) peaks have a different temperature coefficient of frequency shift, and the larger diameter carbon nanotubes have more RBM frequency downshift with increasing temperature. The RBM frequency variation was due to the temperature dependence of the stretching force constant of C-C bond.
