Thermal exchange between two black bodies follows the Stefan−Boltzmann law and at far-field zone the thermalconductivity(per NT length) is described by the equationgSB= (A/L)(π2kB4)/(60ℏ3c2)(T14−T24)/(T1−T2), hereT1,2are the NT and substrate temperatures (giving two fluxes in the opposite directions), the channel area per unit length can be estimated asA/L= 2πR, whereRis a tube radius. In the case of a near room temperature environment (T1= 400 K andT2= 300 K), we obtain:gSB∼ 10− 7W/(K·m), which is much smaller than the bare phonon thermal conductivity in the range ofgo∼ 0.05−0.2 W/(K·m).
