Cu2 In1 Sm1
semiconductor· Cu2 In1 Sm1
Cu₂InSm is an intermetallic compound combining copper, indium, and samarium—a rare-earth ternary system studied primarily in materials research rather than established industrial production. This compound belongs to the family of rare-earth intermetallics and semiconducting materials, with potential applications in thermoelectric devices, magnetic materials, or specialized electronic components where the lanthanide element (samarium) provides magnetic or electronic functionality absent in binary Cu-In systems. The material remains largely experimental; engineers would consider it only for advanced research projects or niche applications requiring rare-earth doping of copper-indium phases.
