Artificial Synaptic Device Based on Self‐Aligned c‐In2O3 TFTs With an Ultrathin MgO Interlayer

Advanced Materials Technologies, EarlyView.
A coplanar synaptic thin‐film transistor based on crystalline In2O3 is demonstrated using a PECVD SiO2 gate insulator and an ultrathin MgO interlayer. The MgO interlayer suppresses excessive carrier density and may facilitate proton‐related interfacial polarization, resulting in stable counterclockwise hysteresis and synaptic behavior.

In Situ Integrated Titanium Oxide Synaptic Phototransistor Enabling Multimodal Plasticity and Noise‐Robust Selective Attention

Advanced Materials Technologies, EarlyView.
An in situ integrated TiO2/SiOx/Al2O3 synaptic phototransistor couples ultraviolet and electrical stimuli within a scalable, CMOS‐compatible oxide stack. Multimodal plasticity, spike‐timing‐dependent learning, and bee‐inspired associative conditioning are achieved through trap‐mediated temporal dynamics.

O Radical‐Induced n‐to‐p Transition in PbS Quantum Dots Enabling Enhanced and Stable Photogating in QD/IGZO SWIR Phototransistors

Advanced Materials Technologies, EarlyView.
An O radical‐induced n‐to‐p transition in PbS quantum dots (QDs) is achieved via atmospheric Ar/O2 treatment, enabling favorable band alignment and stable photogating in PbS QD/IGZO phototransistors. Interfacial defect passivation and Fermi‐level modulation, confirmed by XPS and UPS analyses, effectively suppress dark current, induce a positive VTH ...

Strong Photoluminescence Enhancement in All‐Dielectric Ge Thin Film Metasurfaces for Integration on the Si Platform

Advanced Optical Materials, EarlyView.
Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

Advanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
