Abstract
Frequency (f) and temperature (T) dependence of electrical conductivity σ(f, T) in lightly doped polypyrrole is presented. The behavior of σ(f, T) is different from those of disordered semiconductors and insulating polymers, with considerably strong temperature and frequency dependence of σac.σac changes with ∝f 0.7. These results can be described by slightly modified Kivelson's model, that is, the interpolaron hopping process between the polaron and bipolaron states.Keywords
