Bi4 Br12
semiconductor· Bi4 Br12
Bi₄Br₁₂ is a bismuth halide semiconductor compound belonging to the family of layered perovskite-related materials. This is primarily a research-phase material being investigated for optoelectronic and photovoltaic applications due to its semiconducting properties and potential for tunable bandgap engineering. While not yet commercialized at scale, bismuth halides are of significant interest as lead-free alternatives in next-generation solar cells and light-emitting devices, offering improved stability and reduced toxicity compared to conventional halide perovskites.
