摘要
Electric properties Of Cu7GeS5I and Cu7SiS5I Crystals were studied in a broad temperature (120 - 300 K) and frequency (1 MHz - 3 GHz) ran-e. The ionic conductivity has been distinguished from contact effect. The DC conductivity has been extracted from experimental results. From this DC conductivity the activation energy has been calculated and compared with activation energy obtained from the electrical modulus. (c) 2008 Elsevier B.V. All rights reserved.
