  Low-temperature thermal conductivity and thermopower of multiwalled carbon
nanotubes considered within a bundle of nanotubes are calculated taking into
account multiple scattering of electrons on the atoms of impurities (like
single carbon atoms) and short-range order regions arising due to a some
distribution of the impurities. The calculations are realized on a base of the
temperature diagrammatic Feynman techniques and the results of our research are
in a good quantitative and qualitative agreement with the corresponding
experimental data for multiwalled carbon nanotubes with diameter less or equal
10 nm at T<50K.
