In the present work we studied the ionic conductivity behavior of GeS2-Ga2S3-AgI-Ag chalcogenide system by a random-walk approach [2]. The samples of the nominal compositions [(GeS2)100-x-(Ga2S3)x-(AgI)x]¬100-y-Agy were prepared by Ren et al., as mentioned in [3]. We observed that the conductivity of these glasses increases with increasing content of both AgI and Ag. The observed conductivity obeys Power-law dependence [4]. The activation energy was found to decrease from 0.47 to 0.38 eV with increasing AgI content from 5% to 40%. We also discuss the correlation of diffusion coefficient and mobile ion concentration with AgI concentration.	Random-walk Model , IONIC CONDUCTIVITY
