Cadmium diphosphide (CdP₂) is a compound semiconductor belonging to the III-V and chalcogenide semiconductor families, combining cadmium with phosphorus in a defined stoichiometric ratio. While primarily a research material rather than a widely commercialized compound, CdP₂ is investigated for optoelectronic and photovoltaic applications where its electronic bandgap and optical properties could enable light detection, energy conversion, or quantum device functions. Its development context reflects broader interest in alternative semiconductors for specialized sensing, radiation detection, or next-generation photonic devices where conventional materials (silicon, gallium arsenide) have limitations.
