Background Bismuth-containing III-V semiconductor alloys have received considerable attention as materials for optoelectronic devices operating in the mid- and long-wave infrared spectrum. The infrared spectrum finds important applications in both commerce and government, including medical imaging and diagnostics, autonomous vehicle sensors, telecommunications,...

Infrared photodetectors have a wide range of applications including medical imaging, thermal sensing, spectroscopy, and night vision. Currently, the best photodetectors on the market have an active absorption region made from Mercury Cadmium Telluride (MCT). Although MCT photodetectors maintain the strongest absorption over the greatest spectral range,...
