Ca1 Cu4 As2
semiconductor· Ca1 Cu4 As2
Ca₁Cu₄As₂ is a quaternary intermetallic compound combining calcium, copper, and arsenic in a fixed stoichiometric ratio. This is a research-stage semiconductor material that has been synthesized and characterized in materials science literature, but remains largely experimental with limited commercial deployment. The compound belongs to the family of metal arsenides and represents exploration into novel semiconductor systems for potential electronics and optoelectronics applications, though engineering viability versus mature alternatives (such as III-V semiconductors or silicon-based systems) remains to be established.
