· Ca2 As1 I1

Calcium arsenide iodide (Ca₂AsI) is an emerging semiconductor compound combining alkaline-earth and pnictogen chemistry with halide doping, primarily investigated in materials research rather than established commercial production. This compound belongs to the family of mixed-halide semiconductors being explored for optoelectronic and photovoltaic applications, where iodide substitution can engineer bandgap properties and carrier dynamics compared to conventional arsenide semiconductors. The material represents an experimental platform for understanding how halide incorporation modulates electronic structure in calcium-based semiconductors, with potential relevance to next-generation solar cells and radiation detectors, though practical applications remain largely in the research phase.
