# Monolithically integrated PbS infrared imagers developed in situ

Researchers report PbS infrared imagers integrated monolithically and in situ, avoiding separate detector assembly. The approach could simplify fabrication and support scalable, lower-cost infrared imaging systems. It matters because integrated IR imagers are important for sensing, night vision, and thermal imaging applications.

**Importance:** 3/5
