YbCu2GeSe4
metal· JVASP-155468· YbCu2GeSe4
YbCu2GeSe4 is a ternary intermetallic compound combining ytterbium, copper, germanium, and selenium. This is a research-phase material primarily investigated for its electronic and thermal transport properties, particularly as a potential thermoelectric or semimetallic candidate within the quaternary chalcogenide family. Industrial adoption remains limited; the material appeals to specialized researchers exploring next-generation energy conversion, quantum materials, or semiconductor applications where rare-earth-transition metal combinations offer tunable band structure and low thermal conductivity.
