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)...

Layer Dependent Ferroelectricity and Electromechanically Coupled Polarization in Two-Dimensional 1T′-ReS2

Abstract Two-dimensional (2D) van der Waals (vdW) materials with sliding ferroelectricity exhibit an enormous potential for next-generation nanodevices. Among these, 1T′-ReS2 with an ultralow symmetry stands out as a pivotal candidate. However, the fundamental scientific mechanis...
