Abstract

Electrical conduction in a cellulose triacetate (CTA) is studied as a function of voltage and temperature with three different electrodes: aluminium, copper and silver. The results show that the dominant charge carrier generation mechanism in CTA is of Schottky-Richardson type. The values of the Schottky field lowering constant β, the effective metal-insulator potential barrier and the activation energy involved in the conduction are reported.
