· Mg2 Sc4 Se8

Mg₂Sc₄Se₈ is a ternary semiconductor compound combining magnesium, scandium, and selenium in a layered crystal structure. This is a research-stage material rather than an established commercial compound; it belongs to the family of metal chalcogenides and layered semiconductors being investigated for next-generation electronic and optoelectronic devices. The inclusion of scandium—a rare earth element—and the selenium chalcogenide framework suggest potential applications in high-performance semiconducting systems where tunable bandgap, strong light-matter coupling, or unique electronic properties offer advantages over conventional III-V or II-VI semiconductors.
