Non-Radiative Transitions of Holes on Mercury Vacancies in Narrow-Gap HgCdTe
Mercury vacancies, acting as double acceptors, are the dominant point defects in ternary HgCdTe alloys. Though HgCdTe is one of the leading materials in infrared optoelectronics, the energy spectra of the vacancies are still a matter of some debate. This

ATLAST detector needs for direct spectroscopic biosignature characterization in the visible and near-IR [PDF]
Are we alone? Answering this ageless question will be a major focus for astrophysics in coming decades. Our tools will include unprecedentedly large UV-Optical-IR space telescopes working with advanced coronagraphs and starshades.

Medium wavelength infrared HgCdTe discrete photodetectors
The authors have developed the topology and technological fabrication route for discrete photodiodes (Θ = 0,5—1,5 mm) for the mid wavelength infrared (MWIR) range, based on the mercury-cadmium-telluride (MCT) epitaxial layers.

Rashba spin splitting in biased semiconductor quantum wells [PDF]
Rashba spin splitting (RSS) in biased semiconductor quantum wells is investigated theoretically based on the eight-band envelope function model. We find that at large wave vectors, RSS is both nonmonotonic and anisotropic as a function of in-plane wave ...

Stimulated Emission up to 2.75 µm from HgCdTe/CdHgTe QW Structure at Room Temperature
Heterostructures with thin Hg(Cd)Te/CdHgTe quantum wells (QWs) are attractive for the development of mid-infrared interband lasers. Of particular interest are room-temperature operating emitters for the short-wavelength infrared range (SWIR, typically ...

nBn HgCdTe infrared detector with HgTe(HgCdTe)/CdTe SLs barrier [PDF]
Several strategies have been implemented to improve the performance of infrared single pixel detectors at higher operating temperature condition. The most efficient and effective in HgCdTe technology are: non-equilibrium architectures and currently an idea of the barrier detector to include unipolar and complementary structures.
