Query: Conductance and thermoelectric power in carbon nanotubes with magnetic
  impurities   By introducing a normal self-energy to incorporate the effects of magnetic
impurities, Kondo effects in single-walled metallic carbon nanotubes are
investigated within the Anderson model and Landauer formula. Magnetic
impurities induce Kondo resonance and bring a valley of conductance unction
near the Fermi level. The conductance of the nanotube increases with the
temperature in the low temperature range. Thermoelectric power induced by
magnetic impurities is gotten from Mott relation, and the calculations indicate
its dependence on the temperature could interpret the experiment well.
