Abstract

The a.c. conductivity of semiconducting cis-cisoid polyphenylacetylene (PPA) pellets has been studied at temperatures between 230 and 290 K and frequencies, f{hook}, from 37 to 10⁵ Hz. The a.c. conductivity (σ_a.c.) is found to be strongly temperature dependent. σ_a.c. is proportional to f{hook}^s with s varying from 0.45 to 0.75 as temperature is raised from 230 to 290 K. Both frequency dispersion and strong temperature dependence of σ_a.c. are best explained by the mechanism of hopping conduction in the band-tails.
