AlCuSe₂ is an intermetallic compound combining aluminum, copper, and selenium—a relatively uncommon ternary phase that bridges metallic and semiconductor characteristics. This material is primarily investigated in materials research for potential applications in thermoelectric devices and semiconductor technologies, where its mixed metallic-semiconducting nature may offer advantages in thermal-to-electric energy conversion or specialized electronic applications. Its actual industrial adoption remains limited, making it most relevant to engineers exploring advanced functional materials or working on experimental energy conversion systems rather than conventional structural applications.
