Abstract

The a.c. electrical properties of evaporated V2O5 and co-evaporated V2O5/B2O3 films have been investigated. The conductivity in both types of film follows the theory of Elliott for single polaron hopping. The behaviour of capacitance, tangent of loss angle and dielectric loss agrees with the model proposed by Goswami and Goswami. The co-evaporated films of V2O5/B2O3 show better dielectric properties than simple V2O5 with increasing content of B2O3. Because of their hygroscopic character, the films with B2O3 content larger than 40% are observed to be unstable in the atmosphere.
