These findings shed additional light upon this question and might explain the
importance of free carriers in the conduction band . Although only outlined for (
CH ) n , these considerations are also relevant for other conducting polymers with

Such a strong temperature dependence of the frequency exponent has not been
observed in polymers . Since the optical absorption along the chain direction is
much higher than that perpendicular to it , optically excited carriers give , in ...
