Abstract
The dielectric and electrical properties of Se100-xSx glasses (x=0,5,10,15 and 20) were carried out in the frequency range 0.12-100Â kHz and temperature range 303-393Â K. The frequency dependence of the AC conductivity is found to obey the modified form of the universal power law, Ïâ²=Ï0+AÏs+BÏsâ². The analysis provides an indication of charge hopping mechanism. The influence of composition on the investigated parameters has been reported and attributed to the effect of sulfur fraction on the defect states.
