Effect of thermal annealing on carrier localization and efficiency of spin detection in GaAsSb epilayers grown on InP

open access: yesAIP Advances, 2018
The effect of the thermal annealing on the optical and spin properties in GaAs0.44Sb0.56 epilayers grown on InP was investigated via photoreflectance, power-dependent and time-resolved photoluminescence spectroscopy as well as optical orientation ...

Effect of annealing on the electrophysical properties of CdTe/HgCdTe passivation interface by the capacitance–voltage characteristics of the metal–insulator–semiconductor structures

open access: yesAIP Advances, 2020
The capacitance–voltage characteristics of metal–insulator–semiconductor structures based on Hg1−xCdxTe (x = 0.218) with CdTe passivation are studied before and after the passivation annealing process.

2.6 μm MBE grown InGaAs detectors with dark current of SRH and TAT

open access: yesAIP Advances, 2014
We fabricate 2.6 μm InGaAs photodetectors by MBE technology and study its dark current mechanisms. Deep-level transient spectroscopy (DLTS) demonstrates a deep-level trap located at Ec - 0.25 eV in the absorption layer.

Evaluation of Infrared Detector Response Characteristics Drift Based on Time Sequence [PDF]

open access: yesHangkong bingqi, 2023
The response characteristic drift of infrared detector seriously degrades the imaging quality and system performance. Aiming at the lack of effective evaluation index and difficulty in modeling and evaluating the response characteristic drift of infrared

Infrared: A Meta Bug Detector

open access: yesCoRR, 2022
The recent breakthroughs in deep learning methods have sparked a wave of interest in learning-based bug detectors. Compared to the traditional static analysis tools, these bug detectors are directly learned from data, thus, easier to create. On the other hand, they are difficult to train, requiring a large amount of data which is not readily available.

Investigating reciprocity failure in 1.7-micron cut-off HgCdTe detectors

open access: yes, 2010
Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reciprocity failure over the full dynamic range of near infrared detectors ...

Type II superlattices for infrared detectors and devices [PDF]

open access: yes, 1991
Superlattices consisting of combinations of III-V semiconductors with type II band alignments are of interest for infrared applications because their energy gaps can be made smaller than those of any 'natural' III-V compounds.

An Adjacent Differential Statistics Method for IRFPA Nonuniformity Correction

open access: yesIEEE Photonics Journal, 2013
In this paper, a novel scene-based nonuniformity correction (SBNUC) method using statistics between adjacent detectors for infrared focal-plane array (IRFPA) is proposed. Differential operation is designed as a decorrelation process to minimize the scene

Measurement of infrared optical constants with visible photons

open access: yes, 2018
We demonstrate a new scheme of infrared spectroscopy with visible light sources and detectors. The technique relies on the nonlinear interference of correlated photons, produced via spontaneous parametric down conversion in a nonlinear crystal.
