Sažetak
We present a systematic study of the temperature ($T$) dependence of the dc electrical conductivity of own-made polyaniline pellets doped over a wide range. The dopant is dodecylbenzenesulfonic acid, except for two samples that are fully doped with HCl. A crossover between low-$T$ variable-range hopping and high-$T$ nearest-neighbor hopping has been found below room temperature for most of the samples, which is atypical for conducting polymers. This allows us to construct a diagram that relates various regimes in the hopping electron transport to disorder level and $T$. Our experimentally constructed diagram closely resembles that proposed theoretically by Fogler, Teber, and Shklovskii for the hopping transport in coupled chain-like conductors in the presence of Coulomb interaction. This implies that the model is applicable to conducting polymers if Coulomb interaction is not negligible.
