Broadband asymmetric quantum-well infrared photodetector in Long-Wavelength Infrared Range (LWIR)
(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 µm, ...
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 ...
I-V characterization of a quantum well infrared photodetector with stepped and graded barriers
(Academic Press LTD- Elsevier Science LTD, 2012)
I-V characterization of an n-type quantum well infrared photodetector which consists of stepped and graded barriers has been clone under dark at temperatures between 20-300 K. Different current transport mechanisms and ...
Dark current and optical properties in asymmetric GaAs/AlGaAs staircase-like multiquantum well structure
(Elsevier Science BV, 2013)
In this study, we investigate dark current voltage characteristics of GaAs/AlGaAs staircase-like asymmetric multiquantum well structure at various temperatures experimentally. Measured dark current density voltage (J(d)-V) ...
Broadband staircase quantum well infrared photodetector with low dark current
(Elsevier Science BV, 2006)
We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). It detects wavelengths between 8.8 mu m and 12.3 mu m at an applied electric field of F= 6 x 10(4) V/cm at room ...
