· JVASP-3009· CaZn2As2

CaZn₂As₂ is a ternary ceramic compound belonging to the chalcopyrite-type semiconductor family, composed of calcium, zinc, and arsenic elements. This material is primarily investigated in semiconductor physics and materials research for potential optoelectronic and photovoltaic applications, though it remains largely in the experimental phase compared to more established III-V or II-VI semiconductors. Engineers would consider this compound for niche applications requiring specific band gap properties or lattice parameters that differ from conventional alternatives like GaAs or CdZnTe.
