eng	Ionic conductivity study of LiI-Ga2S3-GeS2 chalcogenide system by random-walk approach	The study of ion-conducting glasses is extremely important because these glasses can be easily fabricated into complex shapes and have a wide compositional flexibility to optimize their properties and conductivities. Chalcogenide glasses (ChGs) containing LiI or AgI have emerged as promising candidates for fast ionic conductors and optoelectronic materials of unique properties [1]. In fact, ChGs containing LiI, such as LiI-Li2S-GeS2-Ga2S3, are one of the best solid state electrolytes known up to date. Li-containing electrolytes are difficult to prepare and environmentally hazardous because of their poor chemical and thermal stability. We are trying to replace Li by Ag metal, since Ag-containing chalcogenides also were studied and showed a good ionic conductivity [1, 2]. In the present work we studied the ionic conductivity behavior of GeS2-Ga2S3-AgI-Ag chalcogenide system by a random-walk approach [2].	Ionic conductivity, impedance analysis
