Realization of a ROIC for 72x4 PV-IR detectors [PDF]

open access: yes, 2008
Silicon Readout Integrated Circuits (ROIC) for HgCdTe Focal Plane Arrays of 1x4 and 72x4 photovoltaic detectors are represented. The analog circuit blocks are completely identical for both, while the digital control circuit is modified to take into ...

Commentary: JWST near-infrared detector degradation— finding the problem, fixing the problem, and moving forward

open access: yesAIP Advances, 2012
The James Webb Space Telescope (JWST) is the successor to the Hubble Space Telescope. JWST will be an infrared-optimized telescope, with an approximately 6.5 m diameter primary mirror, that is located at the Sun-Earth L2 Lagrange point.

Diffusive-Probabilistic Model for Inter-Pixel Crosstalk in HgCdTe Focal Plane Arrays

open access: yesIEEE Journal of the Electron Devices Society, 2018
A closed-form probabilistic model for inter-pixel crosstalk in planar HgCdTe focal plane arrays is presented, providing simple expressions of crosstalk as function of device parameters like the pixel pitch, the absorber thickness, and the extension of ...

Ion Beam Nanostructuring of HgCdTe Ternary Compound

open access: yesNanoscale Research Letters, 2017
Systematic study of mercury cadmium telluride thin films subjected to the ion beam bombardment was carried out. The evolution of surface morphology of (111) Hg1 − x Cd x Te (x ~ 0.223) epilayers due to 100 keV B+ and Ag+ ion irradiation was studied by ...

Symmetries and weak (anti)localization of Dirac fermions in HgTe quantum wells

open access: yes, 2012
We perform a symmetry analysis of a 2D electron system in HgTe/HgCdTe quantum wells in the situation when the chemical potential is outside of the gap, so that the bulk of the quantum well is conducting.
