HfCuGeAs
metal· JVASP-149641· HfCuGeAs
HfCuGeAs is an intermetallic compound combining hafnium, copper, germanium, and arsenic, representing an experimental quaternary metal system. This material belongs to the family of Heusler-type or half-Heusler intermetallic compounds, which are of significant research interest for potential thermoelectric, magnetic, and electronic applications due to their tunable electronic structure and phase stability. While not yet widely deployed in production engineering, such quaternary intermetallics are being investigated as candidates for next-generation energy conversion devices and functional materials where conventional binary or ternary alloys reach performance limits.
