What is Low-temperature Specific Heat of Single-wall Carbon Nanotubes about?

Previous low-temperature heat capacity measurements down to 2 K give evidence for 1-D quantum confinement of SWNT vibrational modes (J. Hone et al., Science 289 (2000) 1730). We extended the data on the same sample down to 0.1 K. A good fit is obtained up to 4 K with C p 1⁄4 C n T À2 þ 0:043T 0:62 þ 0:035T 3 mJ=gK; where the T À2 term is from nuclear hyperfine interactions in ferromagnetic impurities and the T 3 term originates from intertube coupling in agreement with Hone et al. The origin of the T 0:62 term is unknown. Comparison with the vibrational density of states from inelastic neutron scattering is made.
