· JVASP-53186· LuCuSe2

LuCuSe2 is an intermetallic compound combining lutetium, copper, and selenium, belonging to the ternary metal chalcogenide family. This material is primarily of research interest rather than established industrial use, with potential applications in thermoelectric devices, semiconducting systems, and functional materials where the combination of rare earth and transition metal elements offers tunable electronic and thermal properties. Engineers evaluating this compound should consider it for niche applications requiring specialized electronic behavior or thermal management in specialized research and development contexts rather than high-volume production.
