InFe2CuSe4

InFe2CuSe4 is a quaternary intermetallic compound combining indium, iron, copper, and selenium—a research-phase material belonging to the family of chalcogenide-based metallic compounds. While not yet in widespread commercial production, this material class is of interest in thermoelectric and semiconductor device research, where the combination of metallic and semiconducting character can offer unique electronic transport properties. Engineers would evaluate this compound primarily for emerging applications in energy conversion or specialized electronic devices where conventional alloys and semiconductors prove inadequate.
