· Ca1 Bi1 Au1

CaBiAu is an intermetallic compound combining calcium, bismuth, and gold in a 1:1:1 stoichiometric ratio, belonging to the class of ternary metallic semiconductors. This is a research-phase material primarily investigated for its electronic properties and potential applications in thermoelectric or photovoltaic devices, where the combination of heavy elements (Bi, Au) with an alkaline-earth metal (Ca) offers opportunities for tuning band structure and carrier transport. Limited commercial deployment exists; interest centers on fundamental material science exploration rather than established industrial applications.
