Influence of orientational phase transition in conductivity of fullerene-iodine films

The synthesis and research of intercalated fullerene are greatly significant in understanding for this new molecular modification of carbon. Here we report the results of conductive properties of fullerene-iodine compound films. It is found that there are strong changes in the temperature dependence of the conductivity in range of 240-250 K which can be concerned with orientational phase transition of fullerene molecule. It should be noted that the value of changes of conductivity much more strong than in pure fullerene films.
