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 ...

Polarization current-based reservoir computing utilizing an anti-ferroelectric-like HfZrO2 capacitor

APL Machine Learning
We have experimentally demonstrated the physical reservoir computing by employing the polarization switching current dynamics of an Hf1−xZrxO2 (HZO)-based metal/ferroelectric/metal capacitor with Zr content x = 0, 0.5, and 0.75.

Effect of HZO Thickness Scaling in the Bilayer Ferroelectric Tunnel Junction

ACS Applied Electronic Materials
This study investigates the effects of ferroelectric thickness scaling in a bilayer-structured ferroelectric tunnel junction. It was found that both the remnant polarization and the transport mechanisms exhibit a correlation with the thickness of the ferroelectric film.

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Endurance characteristics of HZO FeFETs with different interface layers

Journal of Physics: Conference Series
Abstract This paper investigates the endurance characteristics of Hf0.5Zr0.5O2 (HZO) ferroelectric field-effect transistors (FeFETs) with SiO2 and Y2O3 interface layers. FeFETs have emerged as a promising candidate for high-density ferroelectric memory development, featuring advantages like non-destructive readout, non-volatility, and ...
