Electrical and optical performance of InAs / AlSb / GaSb superlattice photodetector
(TANGER Ltd., 2015)
We report on electrical and optical performance of InAs/AlSb/GaSb type-II superlattice photodetectors. The detector structure is designed to operate in the MWIR domain with a cut-off wavelength of 4.3 µm at 125 K. The ...
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. ...
Zero-bias offsets in I-V characteristics of the staircase type quantum well infrared photodetectors
(Elsevier Science BV, 2014)
In this work, observed zero-bias offsets in I-V characteristics and differences in J-V characteristics of staircase quantum well infrared photodetectors were investigated. Temperature and voltage sweep rate dependence of ...
High quantum efficiency Type-II superlattice N-structure photodetectors with thin intrinsic layers
(Spie-Int Soc Optical Engineering, 2013)
We report on the development of InAs/AlSb/GaSb based N-structure superlattice pin photodiode. In this new design, AlSb layer in between InAs and GaSb layers acts as an electron barrier that pushes electron and hole wave ...
Low dark current N structure superlattice MWIR photodetectors
(Spie-Int Soc Optical Engineering, 2014)
Commercially available read out integrated circuits (ROICs) require the FPA to have high dynamic resistance area product at zero bias (R(0)A) which is directly related to dark current of the detector. Dark current arises ...
I-V characterization of a staircase quantum well infrared photodetector
(Wiley-V C H Verlag GMBH, 2011)
In this work, a quantum well infrared photodetector structure which consists of three different well thicknesses with three different barrier compositions producing a staircase-like conduction band profile with the reputation ...
