Dynamic Sulfur Reservoir Programs Cation-Exchange Kinetics in PbS Quantum Dots for Short-Wave Infrared Imaging Chips

Abstract Cation-exchange synthesis produces monodisperse PbS quantum dots (QDs), yet its central limitation─precursor preparation and dropwise injection─is usually treated as a practical issue. Here, we recast it as sulfur chemical-potential programming; that is, ethyl ziram (EZ)...

Self‐Passivating Perovskite‐Electrode Interfaces Enabled by Field‐Induced Phase Transformation

ABSTRACT Halide perovskites are promising semiconductors for optoelectronic and radiation‐detection applications, yet their operational stability is often constrained by dynamically uncontrolled electrode/perovskite interfaces under electrical bias. Here, we report a self‐passiva...
