Conductivity and Hall effect measurements in doped polyacetylene

Abstract

Conductivity and Hall effect measurements are reported for polyacetylene films heavily doped with AsF5. The Hall coefficient is anomalously small, however, it is p-type and relatively temperature insensitive in the range 4-300 K indicative of metallic conduction. The effects of film degration by heating and air exposure are also investigated. © 1978.
