· JVASP-12862· In5AgSe8

In5AgSe8 is a ternary intermetallic compound combining indium, silver, and selenium, belonging to the family of semiconductor and thermoelectric materials. This material is primarily of research interest for thermoelectric energy conversion and potential optoelectronic applications, where the combination of metallic (Ag, In) and chalcogenide (Se) elements offers tunable electronic and thermal properties. Its use remains largely experimental, but compounds in this material class are investigated for waste heat recovery systems and solid-state cooling devices where layered or complex crystal structures can reduce thermal conductivity while maintaining reasonable electrical transport.
