Cadmium iodide (CdI₂) is a layered semiconductor compound belonging to the II-VI chalcogenide family, characterized by a layered crystal structure that enables mechanical exfoliation into two-dimensional materials. While primarily investigated in research settings for optoelectronic and quantum applications, CdI₂ is notably used in radiation detection systems, photovoltaic research, and as a precursor material for manufacturing specialized optical components. Engineers consider CdI₂ when designing high-sensitivity detectors, exploring van der Waals heterostructures, or developing next-generation thin-film devices where its layered nature and semiconducting properties offer advantages over bulk alternatives.
