Applicability of the localization-interaction model to magnetoconductivity studies of polyaniline films at the metal-insulator boundary

Abstract

Low temperature (down to 1.5 K) conductivity and high-field (up to 13.09×104Oe) magnetoconductivity measurements were performed on three different polyaniline films doped with two dopant acids. The transport behavior of those systems, which lay on either side of the metal-insulator transition, was investigated within the framework of the localization-interaction model and parameters that can implicitly determine the degree of the disorder present in the systems have been evaluated. The suitability, consistency, and limitations of the model for the study of conducting polymers close to the metal-insulator transition are thoroughly discussed.
