Abstract
The variation of parameter A in the power-law conductivity dependence on the frequency, sigma'(omega) = A omega(s), for chalcogenide glasses (Ag2S)(x)(GeS2)(1-x), where 0 < x less than or equal to 0.5, has been determined experimentally. It is found that the exponent s is tempera ture and frequency dependent. Probable mechanisms of charge transport responsible for the experimentally observed temperature dependent cond uctivity via the temperature dependent parameter A are described and a nalyzed.
