Characterization of a multilayer GaAs/AlGaAs broadband quantum well infrared photodetectors
(2010)In this study, we report on the investigation of two multilayer GaAs/AlGaAs quantum well infrared photodetectors designed for 8-12 µm spectral range detection. Fabricated devices were characterized by current-voltage 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) ... -
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 ... -
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 ... -
I-V characterization of a staircase quantum well infrared photodetector

Voltage Tunable Dual-Band Quantum-Well Infrared Photodetector for Third-Generation Thermal Imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2011)We investigate the theoretical calculations of the voltage tunable dual-band quantum-well infrared photodetector (QWIP) in the long and very long wavelength infrared range (LWIR and VLWIR). The detector consists of two ... -
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 ...
