SrCu2GeS4
metal· JVASP-107148· SrCu2GeS4
SrCu2GeS4 is a quaternary sulfide compound combining strontium, copper, germanium, and sulfur—a research-phase material belonging to the family of metal chalcogenides rather than a conventional engineering alloy. This compound is primarily investigated for its potential in thermoelectric and optoelectronic applications, where its unique crystal structure and electronic properties may offer advantages in energy conversion or photovoltaic devices; however, it remains in experimental development and is not yet widely adopted in mainstream industrial production.
