Simple scaling arguments show how contributions to the electron-phonon coupling strength vary with the number of atoms in a carbon fullerene. Smaller fullerenes have higher curvature, which yields larger electron-phonon coupling. The enhancement in coupling is inversely proportional to the number of atoms in the fullerene molecule. Recent ab initio theoretical results on (Formula presented) fit well within this simple model.
