Y3CuGeSe7
metal· JVASP-49703· Y3CuGeSe7
Y3CuGeSe7 is a ternary intermetallic compound composed of yttrium, copper, germanium, and selenium, belonging to the family of rare-earth-based chalcogenides. This is a research-phase material studied for its potential thermoelectric and semiconducting properties rather than an established engineering material in widespread industrial use. The compound represents exploratory work in solid-state chemistry where rare-earth elements are combined with transition metals and chalcogen semiconductors to engineer electronic band structures and phonon scattering for potential energy conversion or optoelectronic applications.
