· BSb

BSb is a binary semiconductor compound in the boron-antimony material family, which belongs to the III-V semiconductor class. While not widely commercialized compared to gallium arsenide or indium phosphide, BSb and related boron pnictides are investigated for high-temperature electronics, wide-bandgap optoelectronics, and specialized photonic applications where thermal stability and chemical inertness are advantageous. Engineers consider BSb primarily in research and development contexts for extreme-environment devices, though material processing challenges and limited industrial supply chains keep deployment niche relative to established III-V alternatives.
