Dielectric properties of undoped polyacetylene films in a large frequency range
نویسندگان
چکیده
2014 Dielectric measurements were performed in a large frequency range (10-4-10+5 Hz) on undoped cis-polyacetylene samples from several laboratories both with ohmic and blocking contacts. The carrier density is low (2 1016 cm-3) and constant but the mobility is thermally activated with a sample and contact dependent activation energy. A maximum activation energy of about 1.6 eV has been found with blocking contacts on the less conducting samples (5 x 10-12 03A9-1 cm-1). J. Physique 43 (1982) 953-959 JUIN 1982,
