    Broadband asymmetric quantum-well infrared photodetector in Long-Wavelength Infrared Range (LWIR)
    (IEEE Computer Society, 2007) Hostut, Mustafa; Ergun, Yuksel; Sokmen, Ismael
    A theoretical investigation of a GaAs-AlGaAs infrared detector consisting of three asymmetric quantum wells is presented. Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 ?m, 9.5 ?m and 10.8 ?m respectively. Device operation is based on inter-subband bound-to-bound transition. Asymmetry in the quantum wells is shown to give broad band responsivity spectrum at an operating bias.
