We present spatially resolved Raman studies on individual single-walled carbon nanotubes (SWNTs). Samples were comprised of microheaters with integrated and suspended SWNTs. We found the phonon frequency to depend on temperature by domega/dT = -0.0305 cm-1/K. The highest measured local temperature in a SWNT was about 1000 K. Further studies emphasize the effect of temperature on the energy shift of...
