· Se4 Br4

Se₄Br₄ is an experimental semiconductor compound composed of selenium and bromine in a 1:1 ratio, belonging to the chalcogen-halide family of materials. This compound is primarily of research interest for optoelectronic and photonic applications, where mixed chalcogen-halide semiconductors are being investigated for their tunable bandgap properties and potential in light-emitting devices. While not yet widely commercialized, materials in this chemical family show promise as alternatives to traditional semiconductors in niche applications requiring specific optical or electronic characteristics.
