· Ca2 In4 Au2

Ca₂In₄Au₂ is an intermetallic compound containing calcium, indium, and gold, belonging to the class of ternary metallic semiconductors. This is a research-phase material studied primarily for its electronic and structural properties rather than established commercial applications. The compound represents an emerging area of intermetallic research where precious metal inclusion (gold) and rare earth-adjacent elements (calcium, indium) are combined to explore novel semiconductor behavior, with potential relevance to thermoelectric devices, optoelectronics, or advanced electronic materials where tailored band structure and carrier transport are sought.
