| We have measured the temperature-dependent thermal conductivity, kappa( T), of single walled carbon nanotubes from 300 K to 8 K by 3o method. kappa(T) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement with the results obtained by Hone et al. using a standard steady state technique. Also we measured the temperature-dependent thermal conductivity kappa( T) of quartz and SiO2 in the same temperature range (300 K to 8 K) as a standardization tool. Our technique shows promise for the thermal conductivity measurements of many nanostructures with slight modifications. |
