摘要：
In this paper we report the frequency and temperature dependence of ac conductivity and dielectric studies of Se85-xTe15Inx glasses. The measurements have been made on Se85-xTe15Inx (x = 2, 6, 10, 15) in the frequency range 2 kHz to 50 kHz and temperature range 203K and 313K. Results indicate that dielectric dispersion occurs in this frequency and temperature range. The results have been explained on the basis of correlated Barrier Hopping (CBH) model. The dc conductivity increases with increase in temperature for all composition. The Log sigma(dc) versus 1000/T plots are almost straight lines in whole studied temperature range indicative of singly activated phenomena having single activation energy.
