Temperature dependent electrical conductivity of p-doped poly(3,4-ethylenedioxythiophene) and poly(3-alkylthiophene)s
Temperature dependent electrical conductivity of substituted polythiophenes (poly(3,4-ethylenedioxythiophene) PEDOTh and head-to-tail type poly(3-alkylthiophene) HT-P3RTh) has been measured. The electrical conductivity (sigma) of p-doped PEDOTh and HT-P3RTh obeys equations of a type, ln sigma= ln sigma(o) -(T-o/T)(0.25), with the T-o value of about 10(5)-10(7) K.
