چکیده انگلیسی
The Pb9Se71Ge20âxSnx (8â¤xâ¤12) glassy alloys are prepared by melt quenching technique. The dielectric parameters and conductivity behavior of pallets has been studied in the frequency range 500 Hz to 1 MHz with varying temperature well below glass transition temperature. The ac conductivity is found to obey the power law Ïs, where s approaches unity at room temperature and decreases as temperature rises. The conductivity behavior, dielectric constant and loss show the frequency and temperature dependence. The results obtained are discussed in terms of correlated barrier hopping model proposed by Elliot. Correlation between conductive and dielectric behavior of glassy alloy has been observed.
