We measured the electrical and thermal transport properties of a C₆₀ single-molecule junction. A plateau was observed in the electrical conductance around 0.1 G₀ (G₀ = 2e²/h), suggesting the formation of a single-molecule junction. A similar plateau was observed in thermal conductance, which changed abruptly upon junction breakdown. The magnitude of this change was estimated to be 1.15 nW/K. This value is larger than that of conventional organic molecular junctions, suggesting that thermal transport in C₆₀ junctions involves not only phonon contributions but also electronic contributions.
