Abstract
The electrical conductivity and electrical relaxation for Se-S-In glasses have been reported in the frequency range 0.12-100 KHz and in the temperature range 303-390K. The enhancement of dc conductivity with increasing indium content has been attributed to the increase in charge carrier mobility. The ac conductivity is found to obey the modified power law sigma' = sigma(dc) + A omega(S) + B omega(1). The electrical relaxation is represented in electric modulus formalism. The relaxation dynamic is independent of temperature and shows non-Debye nature.
