What is it about?
This work discusses performance improvement in a dielectric grating-integrated HgCdTe-based long-wavelength Auger-suppressed high-operating-temperature (HOT) infrared photon detector to address the issue of soft spectral roll-off, which typically occurs due to the trade-off between carrier collection efficiency and absorption.

Why is it important?
To develop high-operating-temperature (HOT) infrared photon detectors for widespread military and commercial applications.
Perspectives
The proposed architecture is CMOS-compatible but not suitable for a small-pixel IR FPA.
