· JVASP-11077· TbCuSe2

TbCuSe2 is an intermetallic compound combining terbium, copper, and selenium, representing a rare-earth based ternary system with potential thermoelectric and magnetic properties. This material is primarily of research interest rather than established industrial production, studied for applications where rare-earth element functionality and semiconducting or mixed-metal characteristics could provide advantages in specialized electronic or thermal management devices. The material family is notable for exploring unconventional combinations of rare earths with transition metals and chalcogens, offering potential tailoring of electronic band structure and thermal transport properties compared to conventional metallic or ceramic alternatives.
