Surface Passivation of HgTe Nanocrystals Enabling EG/2 Open‐Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection

Advanced Materials, Volume 38, Issue 26, 8 May 2026.
This article explores how the integration of a thin shell, combined with optimized surface chemistry, enables the design of photodiodes based on short‐wave infrared HgTe nanocrystals. These photodiodes achieve an open‐circuit voltage greater than half the optical bandgap, which drastically reduces dark current. The article also explores the integration
