Intrinsic Negative Magnetoresistance and Broadband Photoresponse in Magnetic van der Waals Crystal TaFeTe2

Advanced Science, EarlyView.
2D van der Waals (vdW) materials MM′Te2 with broken symmetry attract great interest for unique magnetic structures and optical‐phonon‐induced phase transitions. We report mechanically exfoliable TaFeTe2 single crystals, exhibiting spin‐glass behavior, intrinsic unsaturated negative magnetoresistance up to 9 T, self‐powered internal photocurrent, and ...

Water‐Assisted Exfoliation of HfO2‐Based Membrane for Flexible Robust Ferroelectric Synaptic Transistors

Advanced Science, EarlyView.
A flexible freestanding HfO2‐based ferroelectric membrane is achieved via a water‐assisted exfoliation technique using a Sr4Al2O₇ sacrificial layer. The BaTiO3/Hf0.5Zr0.5O2/BaTiO3 heterostructure maintains robust ferroelectricity and exhibits reliable synaptic plasticity.

High‐Order Nonlinear Photonic Crystal with Ordered Structures for Giant Enhancement of Frequency Tripling

Advanced Science, EarlyView.
A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...

High‐Efficiency TADF Dendritic Emitters Enabled by Synchronously Inhibiting Degenerated Triplet Excited States and Structural Relaxation Toward Solution‐Processed OLEDs with EQE Over 33%

Advanced Science, EarlyView.
Asymmetrical thermally activated delated fluorescence dendritic emitters are delicately constructed through symmetry breaking strategy, and near‐unity photoluminescence efficiency and excellent reverse intersystem crossing process are achieved via breaking the degeneracy of vibrational levels and boosting the spin flip of triplet excitons.
