metal

· JVASP-35971· LuCuS2

LuCuS2 is a ternary intermetallic compound combining lutetium, copper, and sulfur, representing a rare-earth metal chalcogenide in the research phase rather than an established commercial material. This compound family shows potential in electronic and thermoelectric applications due to the electronic properties imparted by rare-earth elements combined with sulfide chemistry, though industrial adoption remains limited and applications are primarily confined to materials research and solid-state physics investigations.
