· JVASP-2520· CaCd2As2

CaCd2As2 is a ternary ceramic compound belonging to the chalcopyrite-structured family of semiconductors, composed of calcium, cadmium, and arsenic. This material is primarily of research and development interest rather than established industrial production, investigated for its potential in optoelectronic and photovoltaic applications where compound semiconductors offer bandgap tunability and direct electronic properties. The material represents an exploratory candidate in the broader class of II-IV-V semiconductors, competing with more mature alternatives like gallium arsenide and cadmium telluride for specialized photon-emission and photon-detection roles in infrared and visible wavelength ranges.
