· JVASP-92308· YbCu2S2

YbCu₂S₂ is an intermetallic compound combining ytterbium, copper, and sulfur, belonging to the family of rare-earth metal chalcogenides. This is primarily a research material studied for its electronic and thermal transport properties rather than a production engineering material; it represents the broader class of rare-earth-transition metal sulfides of interest for thermoelectric and semiconducting applications where tunable band structure is advantageous.
