recommendations! Published in 2017 at "Journal of Electronic Materials"

DOI: 10.1007/s11664-017-5586-6

Abstract: Ultra-low-doped mercury cadmium telluride (HgCdTe, or MCT) is of significant interest for infrared detectors designed to suppress Auger recombination. Measurement of low doping levels in multi-layered structures is difficult with traditional 4-point Hall effect measurements.… read more here.

DOI: 10.1038/s41598-020-62433-w

Abstract: Polarization-independent dielectric meta-lens is proposed to monolithically integrate with a HgCdTe infrared photodetector to concentrate power flux into a reduced photosensitive area for performance enhancement. Although a reduction in photosensitive area could suppress the dark… read more here.
