Observation of Crossover from Three to Two Dimensional Variable Range Hopping in Template Synthesized Polypyrrole and Polyaniline

Abstract

We report the results of a temperature dependent study of the resistance of template synthesized polyaniline and polypyrrole. Depending on the diameter of the template synthesized cylindrical fibers we observe a crossover from three to two dimensional variable range hopping. Two dimensional variable range hopping has been observed before only in ultrathin films (less than 400nm) of amorphous silicon and germanium, but not in Polymer films.
