Current-voltage characteristics of polymer-metal granular thin films in the dielectric regime of conduction were measured in the temperature range from 13 K to room temperature. Non-ohmic behaviour was observed at the lowest temperatures. The curves were fitted by a relationship derived from a direct tunnelling model. We show that estimates of the activation energy of the dominant charge transfer process can be obtained from the parameters of the fit.

Abstract
Current-voltage characteristics of polymer-metal granular thin films in the dielectric regime of conduction were measured in the temperature range from 13 K to room temperature. Non-ohmic behaviour was observed at the lowest temperatures. The curves were fitted by a relationship derived from a direct tunnelling model. We show that estimates of the activation energy of the dominant charge transfer process can be obtained from the parameters of the fit.File in questo prodotto:
