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 ...

In Situ Diffuse Reflectance Infrared Fourier-Transform Spectroscopy Investigation of 1-Methylcyclopropene Adsorption in Cobalt-Formate Metal-Organic Framework. [PDF]
ChemistryOpenIn situ diffuse reflectance infrared Fourier‐transform spectroscopy spectroscopy was used to investigate 1‐MCP adsorption in the pores of Co3(HCOO)6 (Co‐FA) metal–organic framework (MOF). A strong confinement of 1‐MCP at room temperature and a significant release by moderate heating, proves Co‐FA as a promising material for food preservation ...

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.
