Sb4 S4 Br4
semiconductor· Sb4 S4 Br4
Sb₄S₄Br₄ is an experimental mixed-halide chalcogenide semiconductor combining antimony, sulfur, and bromine in a layered crystal structure. This compound belongs to the family of chalcohalides under active research for optoelectronic and photovoltaic applications, where the inclusion of both chalcogen (S) and halide (Br) elements offers tunable bandgaps and potential advantages in light absorption and charge transport compared to single-anion semiconductors.
