Survey of chalcogenide superconductors

The thread that runs through all research in the field of superconductivity is new physics through discovery of new materials. The knowledge of superc onducting materials has become voluminous and complex. The comprehensive re view of the superconducting materials is of particular importance. The main purpose of this report is to present the results of classification for cha lcogenide superconductors. Superconducting critical temperature T-c, crysta l-structure type and the references proper to these compounds are summarize d. Brief survey of the superconductivity in chalcogen elements is also give n. Furthermore, as representative sulfide and selenide, superconducting cha racteristics of CuRh2S4 and CuRh2Se4 will be shown.
