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

AIP 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

AIP 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.

Near-Infrared InGaAs Detectors for Background-limited Imaging and Photometry [PDF]

, 2014
Originally designed for night-vision equipment, InGaAs detectors are beginning to achieve background-limited performance in broadband imaging from the ground. The lower cost of these detectors can enable multi-band instruments, arrays of small telescopes,

An Adjacent Differential Statistics Method for IRFPA Nonuniformity Correction

IEEE 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

, 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.

Impacts of The Radiation Environment At L2 On Bolometers Onboard The Herschel Space Observatory

, 2011
We present the effects of cosmic rays on the detectors onboard the Herschel satellite. We describe in particular the glitches observed on the two types of cryogenic far- infrared bolometer inside the two instruments PACS and SPIRE.

Equivalent efficiency of a simulated photon-number detector [PDF]

, 2001
Homodyne detection is considered as a way to improve the efficiency of communication near the single-photon level. The current lack of commercially available {\it infrared} photon-number detectors significantly reduces the mutual information accessible ...

MoS2-HgTe Quantum Dot Hybrid Photodetectors beyond 2 μm [PDF]

, 2017
Mercury telluride (HgTe) colloidal quantum dots (CQDs) have been developed as promising materials for the short and mid-wave infrared photodetection applications because of their low cost, solution processing and size tunable absorption in the short wave-

Study of thermal stresses in InAs/GaSb type-II superlattice focal plane arrays via multi-scale finite element modeling

AIP Advances
The thermal stress, significantly impacting the performance of infrared detectors, is typically caused by the thermal mismatch between adjacent materials.
