Paper Abstract

High performance long-wavelength GaAs/AlxGa1-xAs quantum well infrared photodetectors for low background applications have been demonstrated. This is the first theoretical analysis of quantum well infrared photodetectors for low background applications and the detectivity D* of 6 X 1013 cm(root)Hz/W has been achieved at T equals 40 K with 2 X 109 photons/cm2/sec background. In addition, this paper describes the demonstration of mid- wavelength/long-wavelength dualband quantum well infrared photodetectors and long-wavelength/very long-wavelength dualband quantum well infrared photodetectors in 4 - 26 micrometer wavelength region.
