One of the most important properties of some chalcogenide systems is their notable glass forming ability in broad composition ranges. Chalcogenide glasses have many technological applications as a result of their particular optic and electrical properties, e.g.: most of IV-VI basedglasses present an optical and electrical switching between two states: the glass and the crystalline state meanwhile several IV-VI glasses containing Ag or Li present, as a function of metal composition, a transition in electric transport from semiconductor to fast ionic conductor. The understanding of the glass structure, its transport properties, glass-crystal transition and its transformation kinetics is essential for these glasses application in non-volatiles memories as well as in solid state electrolytes
