This course will be taught during the Spring semester of 2011. It will provide a broad overview of chalcogenide glasses, which are a technologically important, high-tech sub-class of inorganic glasses that exhibit numerous unusual properties not found in common (oxide) glasses. The course will focus on distinctive characteristics (structure and properties) of chalcogenide glasses and how they lead to broad range of existing and potential applications in photonics, electronics, ionics, etc.
