Interest on the nonlinear optical (NLO) switches that turn on/off second-harmonic generation (SHG) triggered by external stimulus (such as heat) have continuously grown, especially solid-state NLO showing superior stability, reversibility, and reproducibility. Herein, we discover (NH4)2PO3F, an entirely new switch outstanding contrast reversibility well strong SHG intensity (1.1 × KH2PO4 (KDP)) high laser-induced damage threshold (2.0 KDP), undergoes a unique first-order phase transition...
The application of reversible deactivation radical polymerization techniques in 3D printing is emerging as a powerful method to build "living" polymer networks, which can be easily postmodified with various functionalities. However, the building speed these systems still limited compared commercial systems. Herein, digital light processing (DLP)-based system via photoinduced free radical-promoted cationic addition-fragmentation chain transfer vinyl ethers, objects by DLP printer at...
Abstract Perovskite‐oxide‐based ferroelectric tunnel junctions (FTJs) hold great potential for applications in non‐volatile memory and neuromorphic computing due to their unique properties. However, the challenges synthesizing high crystalline quality perovskite oxides directly on silicon wafer limit of these FTJs conventional Si‐based integrated circuits, let alone neural networks.

Tuning the ferroelectric domain structure by a combination of elastic and electrostatic engineering provides an effective route for enhanced piezoelectricity. However, epitaxial thin films, clamping effect imposed substrate does not allow aftergrowth tuning also limits electromechanical response. In contrast, freestanding membranes, which are free constraints, enable subtle balance between energies, giving new platforms tunable functionalities. Here, highly piezoelectricity is demonstrated...
