| Abstract: | We present the result of a theoretical analysis of the phonon contribution to the specific heat for both pure C-60 and alkaline doped K3C60 fullerenes. This is based on the construction of the phonon density of states through the solution of the dynamical matrix, using a Born-Mayer type potential, for the different points in the Brillouin zone. Our results show the contribution to the specific heat for the different modes and in particular we study the low-lying modes coming from intramolecular motions appearing at low temperatures. |
