Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

Advanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

Advanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Millisecond Spin Relaxation Times of Distinct Electron and Hole Subensembles in MAxFA1−xPbI3 Perovskite Crystals

Advanced Science, EarlyView.
Mixed‐cation MAx${\rm MA}_x$ FA1−x${\rm FA}_{1-x}$ PbI3${\rm PbI}_3$ perovskite crystals reveal multiple discrete electron and hole spin subensembles associated with distinct localization environments. Optically detected magnetic resonance combined with resonant spin inertia uncovers carriers spin relaxation times reaching 2 ms and identifies nuclear ...

Green and Scalable Synthesis of Efficient and Stable CsPbBr3 Perovskite Quantum Dots Enables Low‐Threshold Amplified Spontaneous Emission

Advanced Science, EarlyView.
Green and scalable synthesis of CsPbBr3 perovskite quantum dots using bio‐sourced lecithin and hexane enables single‐batch production over 10 grams. Suppressed Auger recombination and electron‐phonon coupling yields 95% PLQY, enhanced stability, and low ASE thresholds of 230.4 (ns) and 50.1 (fs) µJ cm−2 in neat films. ABSTRACT Halide perovskite quantum
