Review of Photodetectors for Space Lidars [PDF]
SensorsPhotodetectors play a critical role in space lidars designed for scientific investigations from orbit around planetary bodies. The detectors must be highly sensitive due to the long range of measurements and tight constraints on the size, weight, and ...

Comparison of performance limits of the HOT HgCdTe photodiodes with colloidal quantum dot infrared detectors [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 In the past decade, there has been significant progress in development of the colloidal quantum dot (CQD) photodetectors. The QCD’s potential advantages include: cheap and easy fabrications, size-tuneable across wide infrared spectral region, and direct ...

Trends in Performance Limits of the HOT Infrared Photodetectors
Applied Sciences, 2021 The cryogenic cooling of infrared (IR) photon detectors optimized for the mid- (MWIR, 3–5 µm) and long wavelength (LWIR, 8–14 µm) range is required to reach high performance. This is a major obstacle for more extensive use of IR technology.

Non-Radiative Transitions of Holes on Mercury Vacancies in Narrow-Gap HgCdTe
Photonics, 2022 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
