Cd2 Au2

Cd₂Au₂ is an intermetallic compound semiconductor formed from cadmium and gold, belonging to the family of binary metal semiconductors with potential applications in specialized electronic and optoelectronic devices. This material remains largely in the research domain, studied for its electronic band structure and phase stability characteristics, rather than as a mature commercial material. Interest in cadmium-gold intermetallics stems from their potential use in high-frequency electronics and photonic applications, though cadmium's toxicity and regulatory restrictions limit widespread industrial adoption compared to alternative III-V or II-VI semiconductor systems.
