Cd4 Bi4 Se8 Br4
semiconductor· Cd4 Bi4 Se8 Br4
Cd₄Bi₄Se₈Br₄ is a mixed-halide quaternary semiconductor compound combining cadmium, bismuth, selenium, and bromine in a layered crystal structure. This is a research-phase material belonging to the family of halide perovskites and related semiconductors, investigated primarily for optoelectronic and photovoltaic applications where tunable bandgap and halide compositional flexibility offer design advantages over binary or ternary semiconductors. Its potential lies in solar cells, photodetectors, and light-emitting devices where the bromide-selenide combination may provide improved stability or optical properties compared to all-iodide or all-bromide analogs.
