· JVASP-56802· Tb3CuGeSe7

Tb3CuGeSe7 is an intermetallic compound combining terbium (a rare-earth element), copper, germanium, and selenium. This material is primarily a research compound rather than an established industrial product, investigated for its electronic and thermal properties within the rare-earth intermetallic family. Its potential applications lie in thermoelectric devices, magnetic materials, and advanced semiconductors where rare-earth elements provide unique electronic band structures and magnetic behavior unavailable in conventional alloys.
