Web1 de ago. de 2024 · The nBn detector PSD (f) at low frequency is assumed to be an upper limit since the contribution from external sources, such as temperature fluctuation from the window, cryocooler and black body, is neglected and the detector on and detector off data were not recorded simultaneously. Web5 de ago. de 2024 · We report design, growth, and characterization of midwavelength infrared nBn photodetectors based on a type-II InAs/InAs1-xSbx superlattice on a GaSb substrate grown by metal-organic chemical...
nBn extended short-wavelength infrared focal plane array
WebnBn sensor technology allows higher operating temperatures with similar performance to InSb. This allows using smaller coolers with longer cooler lifetimes and lower power consumption. The nBn material long wave cutoff wavelength can be tuned from below 2 µm to longer MWIR wavelengths. WebThe super- lattice based barrier infrared detectors described and demon- strated herein have spectral ranges covering the entire 3-5 micron atmospheric transmission window, excellent dark current characteristics operating at least 150K, high yield, and have the potential for high-operability, high-uniformity focal plane arrays. 20 Claims, 23 … razor cut black female hair
