IMAGE BESTNIT SWIR camera based on HgTe quantum cascade detectorAMMJENACIONAL
The Institute of Nano Sciences from CNRS-Sorbonne University is currently researching and producing quantum dot materials of HgTe, sensitive in the extended SWIR wavelength range. Through a partnership with NIT, a first sensor-camera was produced. This technology is promising to design low-cost and small pixel pitch focal plane array, as well as to expand the spectral range of the SWIR camera up to 2.5 µm. This collaborative program is funded by the French National Research Agency. This video presents the technology of quantum cascade detector (QCD) deposition with response up to 2um on NIT ROIC’s, and sample results images in various conditions. A related paper titled "Photoconductive focal plane array based on HgTe quantum dots for fast and cost-effective short-wave infrared imaging" is in the June 2022 issue of Nanoscale journal. Abstract: HgTe nanocrystals, thanks to quantum confinement, present a broadly tunable band gap all over the infrared spectral range. In additio
