Abstract The conductive properties of the conjugated polymer polythiophene doped with FeCl3 are studied as a function of frequency co/2n, electric field E, temperature T and dopant concentration c. The data show a transition from quasi-one-dimensional (for low doping levels) to three dimensional (for high doping) variable range hopping. At all doping levels the macroscopic carrier mobility μ is determined by inter-chain hopping.

. We present a model which quantitatively explains the observed crossover from quasi-one-dimensional transport to three-dimensional hopping conduction with increasing doping level. At high frequencies the conductivity is dominated by charge transport on one-dimensional conducting chains.
