HgZnTe-based detectors for LWIR NASA applications [PDF]
The initial goal was to grow and characterize HgZnTe and determine if it indeed had the advantageous properties that were predicted. Researchers grew both bulk and liquid phase epitaxial HgZnTe. It was determined that HgZnTe had the following properties:

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Chlorofluorocarbons (CFCs) have played a major role in the depletion of stratospheric ozone. Understanding historical trends in emissions and atmospheric concentrations is crucial for quantifying their impact. The first measurements of atmospheric CFCs were performed in‐situ by Lovelock in 1970.

Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy
Advanced Materials, Volume 38, Issue 7, 2 February 2026.SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well
