As a laser module manufacturer, we have been studying and focusing on the development of the product industry.
The nBn structure design for infrared detector can be used to eliminate both Shockley-Eead-Hall generation currents and surface recombination currents, which will lead to a higher operating temperature, so it has attracted the attention of many research institutions around the world.
The sb-based nBn structure infrared detector had developed rapidly, and some infrared detectors with this structure have achieved the working temperature of 150k or more.
The working principle of Sb-based nBn infrared detector, structural advantages and development status are summarized, which provides a good prediction for future development of high temperature are high performance infrared focal plane detector.
