Thermodynamic Stabilization of PbS Quantum Dots for High-Performance Short-Wave Infrared Photodetection.

The development of lead sulfide (PbS) quantum dot (QD) photodetectors for short-wave infrared (SWIR) applications has been fundamentally limited by the thermodynamic instability of large PbS QD facets, which leads to aggregation and epitaxial fusion. In this work, robust thermodynamic stabilization was achieved by intr...
