Broadband staircase quantum well infrared photodetector: working in long wavelength infrared range (LWIR)
(WILEY-V C H VERLAG GMBH, 2007)
We present a theoretical investigation of a staircase-like quantum well infrared photodetector (QWIP). it detects wavelength between 7.6 mu m and 13.5 mu m range at an applied electric field of F = 1.9x10(4) V/cm at 77 K. ...
Broadband asymmetric quantum-well infrared photodetector in long-wavelength infrared range (LWIR)
(IEEE, 2007)
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 pro, ...
