AC conductivity spectra of KCl: In crystals. Temperature dependent deviations from the Summerfield scaling

Journal of Optoelectronics and Advanced Materials (Impact Factor: 0.52). 07/2004; 6:465-469.

ABSTRACT The application on the Summerfield scaling law does not lead to a superposition of the conductivity isotherms of KCl:In crystals, but the isotherms are shifted to higher values on the T dc σ ν axis as the temperature deceases. The isotherms, however, do collapse onto a single master curve when an additional scaling factor α T with ] 1 2 . 1 [ ÷ ÷ ÷ ÷ ∈ ∈ ∈ ∈ α is used for frequency axis. The exponent α decreases with temperature. The results of this scaling procedure have been obtained considering the shape of the isotherms being independent of composition.
