Název v původním jazyce

Ionic conductivity study of LiI-Ga2S3-GeS2 chalcogenide glasses using a random-walk approach

Popis výsledku v původním jazyce

Electrical properties of a set of lithium-ion conducting sulfide glasses with general formula 20LiI-xGa2S3-(80-x)GeS2 (x = 10, 15 and 20) is studied in the present article. The experimental data obtained using impedance spectroscopy are analyzed by meansof a random-walk (RW) model assuming that the conduction takes place by a random motion of Li+ ions. The influences of added gallium on the structural network and on the conductivity of prepared glasses are also analyzed using the RW model. The resultsare further confirmed by Raman spectral analysis. The results obtained by the random-walk model and by a conventional equivalent electric circuit model are in a good agreement. We observed that the addition of Ga2S3 contributed to phase separation in theprepared glassy system and negatively influenced the conductivity of the studied glasses. Factors contributing to the total conductivity with respect to the amount of both LiI and Ga2S3 are also reported.
