Electron scattering rates in metallic single-walled carbon nanotubes are studied using an atomic force microscope as an electrical probe. From the scaling of the resistance of the same nanotube with length in the low- and high-bias regimes, the mean-free paths for both regimes are inferred. The observed scattering rates are consistent with calculations for acoustic-phonon scattering at low biases and zone boundary/optical phonon scattering at high biases.

Electrical and thermal transport in metallic single-wall carbon nanotubes on insulating substrates (2006, background): “The breakdown current of metallic SWNTs longer than about 1 μm with good electrical contacts is wellknown to be generally very close to IBD ≈ 20 μA when laying on insulating substrates, as observed by previous researchers [14-16] as well as in the course of this work.”
Energy dissipation and transport in nanoscale devices (2010, background): “where R0 is the quantum of electrical resistance defined above, λOP = L(ħωOP/qV) + λ0, and λ0 is the spontaneous OP emission MFP for carriers with energy E > ħωOP [29, 30] (for example, λ0 ≈ 15d for a carbon nanotube with diameter d [31]).”
