Growth and fabrication issues of GaSb-based detectors

Antimony-based semiconducting materials are of great interest to the research and technology development communities for mid- and long-infrared applications. In particular, the antimony-based detector is a key component in advanced high-speed and low-noise optical receiver systems. However, the growth and fabrication of antimony-based detectors face several challenges, of which, the most important is the reduction of surface leakage which …
