Pb4 Se1 Br6
semiconductor· Pb4 Se1 Br6
Pb₄Se₁Br₆ is a mixed-halide lead chalcogenide semiconductor compound combining lead, selenium, and bromine in a layered perovskite-like structure. This is primarily a research material being investigated for optoelectronic applications, particularly in the context of lead-halide perovskite alternatives and solid-state radiation detection; the selenium substitution and bromine incorporation are being explored to engineer bandgap, stability, and carrier transport properties relative to more-studied lead-iodide perovskites.
