Design of a quantum well detector for the 8-14 micron wavelength region

The use of quantum well structures for infrared detection in the 8-14 micron range has recently become a practicality. The device is based on infrared absorption between subbands within the conduction band of a GaAs quantum well. In this paper, some elements of the design of these detectors are disc...

Summary:The use of quantum well structures for infrared detection in the 8-14 micron range has recently become a practicality. The device is based on infrared absorption between subbands within the conduction band of a GaAs quantum well. In this paper, some elements of the design of these detectors are discussed, including the effect of well width and AlGaAs barrier height and width on the sensitive wavelength. (Author)
