Electrical conductivity of semiconducting V₂O₅-GeO₂glasses

Abstract

Abstract The DC conductivity of semiconducting vanadium germanate glasses of compositions in the range of 40-70 mol(%)V2O5has been measured in the temperature region 300-530 K. Measurements have been made on unannealed samples and some samples annealed at 300°C. Annealing the samples at temperatures of about 300°C causes the appearance of a crystalline phase resulting in an increase of conductivity. The crystalline temperature has been estimated from the conductivity data for unannealed samples. These seem to be in reasonable agreement with the corresponding results found in the literature.
