Abstract

Six (chalcogen)1−x glasses represent a class of amorphous, binary, semiconducting solids of increasing theoretical and technological importance. In our laboratory, attention has been directed to these systems since they can form the basis of a remarkable series of fast ion conducting glasses. These vitreous materials are being considered as solid electrolytes for advanced electrochemical cells of high specific energy. For example, when stoichiometric SiS 2 is appropriately combined with Na2S, a Na-ion conducting glass results that has a room-temperature Na-ion conductivity that is several orders of magnitude greater than that of its oxide counterpart [1].The structures and defects present in these alkali-modified, ternary glasses are not known [2]. In fact, until recently, there has been a paucity of attention directed to the “simple” binary glass systems Si/S, Si/Se, and Si/Te. Therefore, four years ago, we began a systematic study of the structure and dynamics of Si xS1 SixSe1−x, and SixTe1−x covalent glasses. Of necessity, an interdisciplinary approach was adopted.
