· JVASP-155384· Cu2NiGeS4

Cu2NiGeS4 is a quaternary sulfide compound combining copper, nickel, germanium, and sulfur elements, belonging to the family of metal chalcogenides. This is a research-phase material studied primarily for its electronic and photovoltaic properties rather than as an established engineering material in widespread industrial use. Interest in this compound centers on potential applications in thermoelectric energy conversion, photovoltaic devices, and optoelectronic systems where the interplay of multiple metallic elements in a sulfide matrix offers tunable band gaps and carrier transport characteristics.
