Sub‐Nanometer Ferroelectric Tunnel Junctions With Record‐High on‐Current Density Through Synergistic Microwave Annealing and High‐Field Activation

Small, EarlyView.
ABSTRACT High‐density memory systems require a high on‐state current density (Jon) to ensure fast read speeds and large sensing margins in cross‐point array applications. However, achieving high Jon in atomically thin ferroelectric tunnel junctions (FTJs) remains an unmet challenge, hindered by parasitic interfacial layer (IL), depolarization fields ...

A Bilayer Rare‐Earth/High‐κ Oxide Memristor for Energy‐Efficient Neuromorphic Intelligence

Small, EarlyView.
Interface‐engineered Gd2O3/HfO2 bilayer memristors demonstrate controlled filament formation, ultralow switching energy (∼13.56 pJ), and fast operation (∼350 ns) with a high ON/OFF ratio (∼107). The devices exhibit stable analog synaptic behavior and enable pattern recognition on Fashion‐MNIST, underscoring their promise for energy‐efficient ...

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

Small, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...
