Optically Switchable Fluorescence Enhancement at Critical Interparticle Distances

Advanced Theory and Simulations, EarlyView.
In this work, we present the results of a complete FDTD (Finite Difference Time Domain) model specifically tailored for the precise determination of critical interparticle distances yielding observable fluorescence enhancement. We further report an optical switch applied on a metal nanoparticle to actively control the radiative decay rate of a closely ...

Design of CsSnBr3/Ga2O3 Hybrid Photodetectors for High UV Selectivity and Bifacial Usage

Advanced Theory and Simulations, EarlyView.
A numerical study investigates a lead‐free CsSnBr3/Ga2O3 p–n heterojunction photodetector, analyzing its electrical and optoelectronic performance. High illumination‐to‐dark current ratios and rectification are achieved. The device operates in self‐powered, bifacial, solar‐blind, and UV–Vis modes with strong responsivity and detectivity.

Spontaneous Strain‐Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High‐κ and Switchable Dielectric Permittivity

Advanced Science, EarlyView.
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Boosts in Polarization and Piezoelectric Responses of Lead‐Free Ferroelectrics through Strain‐Enhanced Glassy Coexistent Polars with High Dynamics

Advanced Science, EarlyView.
An effective strategy by constructing strain‐enhanced glassy coexistent polars near ferroelectric tricritical point to simultaneously improve polarization response and reduce energy loss is uncovered in (Ba0.84Ca0.16)0.985Bi0.01(Ti0.9Zr0.07Sn0.03)1‐x/100Hfx/100O3 (xHf) system and verified by phase‐field simulations with supporting high resolution ...
