Abstract
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 Ω-1 cm-1)Keywords
