High performance bias-selectable three-color Short-wave/Mid-wave/Long-wave Infrared Photodetectors based on Type-II InAs/GaSb/AlSb superlattices
TL;DR: A new approach in device architecture to realize bias-selectable three-color shortwave-midwave-longwave infrared photodetectors based on InAs/GaSb/AlSb type-II superlattices is proposed, retaining the simplicity in device fabrication and opening the prospect for three- color infrared imaging.
Journal ArticleDOI
Type–II superlattices base visible/extended short–wavelength infrared photodetectors with a bandstructure–engineered photo–generated carrier extractor
TL;DR: Visible/extended short–wavelength infrared photodetectors with a bandstructure–engineered photo–generated carrier extractor based on type–II InAs/AlSb/GaSb superlattices have been demonstrated, with sensitivity down to visible wavelengths.

TL;DR: In this paper, a simple synthesis of MFe 2 O 4 (where M = Zn, Mn and Co) nanostructures by a thermal treatment method, followed by calcination at various temperatures from 723 to 873 K polyvinyl pyrrolidon (PVP) was used as a capping agent to stabilize the particles and prevent them from agglomeration.
Journal ArticleDOI
Bias-selectable nBn dual-band long-/very long-wavelength infrared photodetectors based on InAs/InAs1-xSbx/AlAs1-xSbx type-II superlattices.
TL;DR: This design uses two different bandgap absorption regions separated by an electron barrier that blocks the transport of majority carriers to reduce the dark current density of the device, and will open new opportunities for multi–spectral LWIR and VLWIR imaging and detection.
Journal ArticleDOI
Preparation, Characterization and Thermal Degradation of Polyimide (4-APS/BTDA)/SiO2 Composite Films
Mansor Bin Ahmad,Yadollah Gharayebi,Yadollah Gharayebi,Mohd Sapuan Salit,Mohd Zobir Hussein,Saeideh Ebrahimiasl,Arash Dehzangi +6 more
TL;DR: The results indicated that thermal stability and the values of the calculated activation energies increased with the increase of the TEOS loading and the activation energy also varied with the percentage of weight loss for all compositions.
