| Abstract | Picosecond transient absorption is used to measure the thermal decay time of a mixture of higher-order fullerenes suspended in chloroform, toluene, and carbon disulfide. The relaxation time is 40 ps, which translates into a small effective interface conductance, G 14 MW m_2 K_1. Molecular dynamics simulations of a fullerene molecule suspended in octane agree with experiment (G 10 MW m_2 K_1) and support the conclusion that the 40 ps decay time results from the relaxation of vibrational energy and not the relaxation of electronic excitations. |
