How It Compares
Within the iron-based superconductors class.
Unlike the well-known metallic superconductors such as FeSe, Cl14Fe2Te2 exhibits a semiconducting character that sets it apart from the highly conductive members of the iron-based class. While FeSe and FeTe2 are frequently studied for their magnetic and superconducting transitions, this chloride-rich phase provides a stable, non-metallic alternative for exploring iron-chalcogenide coordination geometries.
