Ca4 Zn4 Cu2 P6

Ca₄Zn₄Cu₂P₆ is a quaternary semiconductor compound composed of calcium, zinc, copper, and phosphorus elements, belonging to the family of mixed-metal phosphide semiconductors. This is primarily a research-phase material studied for its potential electronic and photonic properties; it represents an emerging class of multi-component semiconductors designed to achieve tunable bandgaps and enhanced functionality compared to binary or ternary phosphide systems. The material's combination of earth-abundant elements and flexible compositional design makes it of interest in solid-state physics and materials engineering, though applications remain largely experimental and focused on fundamental property characterization rather than established industrial deployment.
