Lattice specific heat of carbon nanotubes
  The lattice specific heat of carbon nanotubes is evaluated within the microscopic model proposed by Mahan and Jeon, published in the Physical Review B, in 2004. Phonons are considered for a single wall carbon nanotube in the armchair configuration. As expected, low temperature and high temperature regions show different behavior of specific heat. Carbon nanotubes are also displaying a very interesting lattice transport depending on the diameter, with a rather high thermal conductivity for small diameters.
