Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

Advanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Overcoming Material Incompatibility via 2D Free‐Surface Engineering

Advanced Materials, EarlyView.
A scalable post‐epitaxial strategy introduces a sub‐nanometric 2D free surface (2DFS) at the heterointerface, effectively decoupling lattice‐mismatched layers. This process significantly reduces strain‐driven defects and dislocation density in Ge/Si heterostructures. The resulting bulk‐like material quality, validated by advanced microscopy and optical

Terahertz Electronic and Spin Currents in Wafer‐Scale Van der Waals Bi2Se3/WSe2 Heterostructures and Polymorphs

Advanced Materials, EarlyView.
Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Néel Tensor Torque in Polycrystalline Antiferromagnets

Advanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a
