Abstract

Structural and physical properties of layered chalcogenide superconductors are summarized. In particular, we review the remarkable properties of the Fe-chalcogenide superconductors, FeSe and FeTe-based materials. Furthermore, we introduce the recently discovered BiS₂-based layered superconductors and discuss their prospects.

Keywords: BiS2-based superconductor; Fe chalcogenide; FeSe; FeTe; magnetism; superconductivity.
