The electron transport properties of an air-exposed one-dimensional (1D) uneven peanutshaped C60 polymer film were investigated by examining the temperature dependence (30-350 K) of the current-voltage (I-V) characteristics under ultrahigh vacuum conditions. Arrhenius plots of the resistance as a function of temperature showed two different electron conduction mechanisms. At temperatures above 140 K, it was found that electrons are conducted via a thermal excitation hopping mechanism, and the activation energy changed discontinuously from 124 to 99 meV at ca. 190 K because of a change in the 1D polymer chain-chain interactions. On the other hand, at temperatures below 100 K, the electron conduction behavior is consistent with a 2D variable-range hopping mechanism.
