· JVASP-13061· Bi3Se4Br

Bi₃Se₄Br is a mixed halide-chalcogenide ceramic compound combining bismuth with selenium and bromine, belonging to the family of layered bismuth-based materials that are of significant interest in solid-state physics and materials research. This compound is primarily investigated for potential applications in thermoelectric devices, photovoltaic systems, and topological material research, where its unique electronic structure and anisotropic crystal properties could offer advantages in energy conversion and quantum transport phenomena. While not yet widely deployed in mainstream engineering applications, materials in this bismuth chalcogenide-halide family are notable for their tunable band gaps and potential use in next-generation semiconducting and optoelectronic devices.
