· P1 Ca2 I1

P1 Ca2 I1 is a calcium iodide-based semiconductor compound with a simple binary stoichiometry. This material belongs to the family of halide semiconductors, which are of growing interest in optoelectronics and radiation detection applications due to their favorable bandgap properties and relatively straightforward synthesis. Calcium iodide semiconductors are explored primarily in research settings for scintillation detectors, photovoltaic devices, and X-ray/gamma-ray sensing, where they offer potential advantages in cost and manufacturability compared to more complex halide perovskites, though material stability and defect engineering remain active areas of investigation.
