CHALCOGENIDE SEMICONDUCTOR RESEARCH AND APPLICATIONS SYMPOSIUM (AT THE XXVI IMRC 2017)
Abstract
Chalcogenides has its origin in chalkos, a Greek word for bronze, assigned to copperbearing minerals: chalcocite, chalcopyrite, etc. Over time, chalcogenides have come to signify compounds of metals with group-VI elements. Many of these are naturallyoccurring crystals that are born as semiconductors: chalcocite (Cu2S), pyrite (Fe2S), chalcopyrite (CuFeS2), chalcostibite (CuSbS2), herzenbergite (SnS), galena (PbS), etc. They also include materials that are under widespread investigation for devices: transition metal di-chalcogenides (eg. MoS2) for electronics and photonics, Cu(In,Ga)(S,Se)2 and Cu2ZnSnS4 for photovoltaics, (Hg,Cd,Zn)Te for detectors and photovoltaics, Bi2Se3 for topological computing, etc. Chalcogenide semiconductors may be key to advancing many of the technical goals of the Office of Naval Research including materials for nanoelectronics combining new functionalities, phase change materials for microelectronics and RF applications, and materials for infrared imaging. Chalcogenide opto-electronic materials exhibit a wide range of phenomena including layered crystal structures with anisotropic transport, ordering phenomena such as ferroelectricity and density waves, widely tunable band gaps, and strong interactions with light including excitonic effects. Understanding, controlling, and harnessing these phenomena requires a thorough understanding of the science and device implications of chalcogenide electronic materials. There have been conferences in the past devoted to chalcogenide electronic materials, but over the years the theme has splintered into many subthemes. Researchers in this theme share an awareness of the challenges involved in the material preparation and characterization, and a passion for their wide range of applications. Chalcogenide Semiconductor Research and Application (CSRA) symposia are intended to organize and serve the needs of this growing community. The primary outcome of this event will be the creation of a new community of researchers, connecting previously disparate branches of chalcogenide electronic materials research.
