Single‐Atom Intercalation‐Driven Topological Ferroelectric Metal for High‐Performance Hydrogen Evolution Reaction

Advanced Science, EarlyView.
Single‐atom Cu intercalation enables porous AB3 monolayers to integrate ferroelectricity, metallicity, topology, and hydrogen evolution catalysis in one platform. Switchable FE polarization modulates work function and hydrogen adsorption thermodynamics, providing an electrically controllable route to activate basal‐plane HER activity in topological ...

Ferroelectricity in graphene nanoribbon devices enabled by collective water molecule dynamics

Nature Communications
Water is omnipresent in nanoscale systems, yet its collective dynamics and impact on emerging electronics remain poorly understood. Here, we investigate the role of water molecule dynamics in the ferroelectric response of graphene nanoribbon devices. Our

Single Molecular Semi-Sliding Ferroelectricity/Multiferroicity

Research
In recent years, the unique mechanism of sliding ferroelectricity with ultralow switching barriers has been experimentally verified in a series of 2-dimensional (2D) materials. However, its practical applications are hindered by the low polarizations, the challenges in synthesis of ferroelectric phases limited in specific stacking configurations, and ...

From negligible to giant electrocaloric effect of poly(vinylidene fluoride)

Nature Communications
Poly(vinylidene fluoride) (PVDF), the most widely used ferroelectric polymer, typically exhibits a negligible electrocaloric effect (ECE) due to its symmetrical molecular configuration and bulky ferroelectric domains. PVDF-based ferroelectric terpolymers

Ferroelectric AlBN films by molecular beam epitaxy

Applied Physics Letters
We report the properties of molecular beam epitaxy deposited AlBN thin films on a recently developed epitaxial nitride metal electrode, Nb2N. While a control AlN thin film exhibits standard capacitive behavior, distinct ferroelectric switching is observed in the AlBN films with increasing Boron mole fraction.

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...
