Multiwalled carbon nanotube: Luttinger versus fermi liquid

摘要: We have measured $\mathrm{IV}$ curves of multiwalled carbon nanotubes using end contacts. At low voltages, the tunneling conductance obeys non-Ohmic power law, which is predicted both by Luttinger liquid and environment-quantum-fluctuation theories. However, at higher voltages we observe a crossover to Ohm's law with Coulomb-blockade offset, agrees theory, but cannot be explained Luttinger-liquid theory. From high-voltage determine transmission line parameters nanotubes.
