Abstract

Poly(3-methyl thiophene) has been synthesized by chemical oxidation method in an inert atmosphere using ferric chloride as a dopant. The doping level varies from 0.1 to 2.0 M. The dc conductivity has been measured in the temperature range 20-300 K. The observed dc conductivity data has been analyzed in the light of existing theoretical models. Different Mott's parameters such as characteristic temperature (T-0), density of states at Fermi level [N(E-F)], average hopping energy (W) and the average hopping distance (R) have been evaluated that agree well with the values reported earlier for the other conjugated polymers. A detailed analysis of the mechanism of charge transport in this system has been reported. (C) 2002 Elsevier Science B.V. All rights reserved.
