GaBi

Gallium antimonide (GaBi) is a III-V compound semiconductor formed from gallium and antimony, engineered for optoelectronic and high-frequency applications. It is primarily used in infrared detectors, thermophotovoltaic devices, and high-speed transistors where its narrow bandgap and high carrier mobility provide advantages over silicon and wider-bandgap III-V materials. GaBi is notable for sensitivity in the mid- to far-infrared spectrum and for operation at elevated temperatures, making it valuable in thermal imaging, night-vision systems, and space-based sensing where conventional semiconductors fall short.
