· JVASP-103711· In2CuAgSe4

In₂CuAgSe₄ is a quaternary chalcogenide compound combining indium, copper, silver, and selenium—a material class of interest for semiconductor and thermoelectric applications. This is primarily a research-stage compound rather than an established commercial material; the silver-copper-indium selenide family is investigated for potential use in photovoltaic devices, thermoelectric power generation, and optoelectronic components where tunable band gaps and mixed-valence chemistry offer advantages over simpler binary or ternary compounds.
