· Ca3 As1 Br3

Calcium arsenide bromide (Ca₃As₁Br₃) is an experimental halide perovskite-related semiconductor compound combining group II, group V, and halide elements. This material exists primarily in research contexts where it is being investigated for potential optoelectronic and photovoltaic applications, leveraging the tunable bandgap and crystal structure properties characteristic of halide perovskites and related semiconductors. While not yet commercialized, compounds in this family are of interest to researchers exploring next-generation light-emitting devices, photodetectors, and solar cells as alternatives to conventional semiconductors, though stability, toxicity, and scalability remain active research challenges.
