· JVASP-8554· InCuSe2

InCuSe₂ is an intermetallic compound combining indium, copper, and selenium, belonging to the family of ternary metal chalcogenides. This material is primarily investigated in research contexts for semiconductor and thermoelectric applications, where the combination of metallic and semiconducting character offers potential advantages in energy conversion and electronic device design. InCuSe₂ and related ternary chalcogenides are explored as alternatives to traditional semiconductors in niche applications where their unique electronic structure and thermal properties could provide improved performance or cost benefits compared to conventional materials.
