The direct current (DC) conductivity of poly(3-methyl thiophene) was measured in the temperature range of 77-300 K. The observed DC conductivity data were analyzed in the light of Mott's variable range hopping model. Different Mott's parameters such as characteristic temperature (T-0), average hopping distance (R), average hopping energy (W), and density of states at the Fermi level (N [E-F]) were evaluated. By taking the inverse of the coefficient of exponential decay of the localized states involved in the hopping process as 0.5 nm, a realistic value of density of states at the Fermi level (N [E-F]) was obtained that agrees well with the values reported earlier for other conjugated polymers.
