    Abstract

    The electrical conductivity ( sigma ) of polyacetylene, (CH)//x, increases rapidly upon doping, evolving from insulator to metal with exposure to many donors and acceptors. The lack of a sharp insulator-metal transition and the decrease in sigma at low temperature(T) is usually thought due to interfiber contacts or undoped regions resulting in small metal particles in a dielectric medium. The T, f, and electric field (E) dependent sigma of iodine doped (CH)//x are presented for the concentration regime which spans the metal-insulator transition.
