The metal-semiconductor transition of peanut-shaped fullerene (C60) polymers is clarified by considering the electron-phonon coupling in the uneven structure of the polymers. We established a theory that accounts for the transition temperature Tc reported in a recent experiment. The theory also suggests that Tc is considerably lowered by electron doping or prolonged irradiation during synthesis. The decrease in Tc is an appealing phenomenon with regard to realizing high-conductivity C60-based nanowires even at low temperatures.
