· Yb(CuS)3

Yb(CuS)₃ is an experimental ternary chalcogenide semiconductor compound combining ytterbium, copper, and sulfur. This material belongs to the family of rare-earth transition-metal sulfides, which are investigated for thermoelectric, photovoltaic, and optoelectronic applications where bandgap engineering and carrier mobility optimization are critical. Researchers explore such compounds as potential alternatives to commercial thermoelectric materials or for next-generation photovoltaic absorbers, though industrial adoption remains limited and the material is primarily studied in academic and advanced materials research settings.
