Improvement in the quantum sensitivity of InAs/InAsSb/InAsSbP heterostructure photodiodes

Light emitting diode–photodiode optoelectronic pairs based on the InAs/InAsSb/InAsSbP heterostructure for the detection of carbon dioxide

“…Light emitting diodes for opera tion in this spectral range [2,3] and photodiodes with a broad spectral sensitivity band of 1.5-4.8 μm [4] have been fabricated based on these heterostructures. However, the problem of the detection of CO 2 and CO using the above mentioned optoelectronic pairs has not been considered.…”
