· NaCuSe

NaCuSe is an intermetallic compound combining sodium, copper, and selenium—a class of materials of primary interest in solid-state physics and materials research rather than established engineering practice. While not widely deployed in conventional industrial applications, compounds in this family are investigated for their potential in thermoelectric devices, semiconductor physics, and advanced functional materials due to their unique electronic and thermal properties arising from the copper-selenium bonding framework.
