Abstract


The electrical conductivity ac and dc of Se50Te45Ge5 glass were carried out in the frequency range 102–106 kHz and temperature range 100 - 300 K. the. The conductivity properties were explained by microscopic or macroscopic models. . In this paper we demonstrated that both microscopic and macroscopic models can be approached each other if the Meyer-Neldel rule takes into account. For this purpose, the correlated barrier hopping model and percolation path approximation are applied on the conductivity data of Se50Te45Ge5. The experimental results are in quantitative agreement results with theoretical models of CBH and PPA.
