Query: Reducing the thermal conductivity of carbon nanotubes below the random
  isotope limit   We find that introducing segmented isotopic disorder patterns may
considerably reduce the thermal conductivity of pristine carbon nanotubes below
the uncorrelated disorder value. This is a result of the interplay between
different length scales in the phonon scattering process. We use ab-initio
atomistic Green's function calculations to quantify the effect of various types
of segmentation similar to that experimentally produced by coalescence of
isotope-engineered fullerenes.
