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 ...

Standalone Integrated Magnonic Devices

Advanced Materials, EarlyView.
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

Advanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Environmental Control of Ferroelectricity in Hafnia Films

Advanced Materials, EarlyView.
A reversible transition from nonferroelectric to ferroelectric behavior is achieved in hafnia films by modulating the surrounding atmosphere. The domain relaxation dynamics exhibit high sensitivity to environmental factors, including gas composition (ambient, N2, CO2, O2) and relative humidity, highlighting the crucial role of the measurement ...
