Defect enhanced optic and electro-optic properties of lead zirconate titanate thin films

AIP Advances, 2011
Pb(Zr1-xTix)O3 (PZT) thin films near phase morphotropic phase boundary were deposited on (Pb0.86La0.14)TiO3-coated glass by radio frequency sputtering. A retrieved analysis shows that the lattice parameters of the as-grown PZT thin films were similar to ...

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 Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Microstructural Engineering of Sodium Potassium Niobate for Enhanced and Temperature‐Stable Electromechanical Response

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
This study investigates the synergistic effects of Ti‐doping and K5.4Cu1.3Ta10O29 (KCT) co‐modification on KNN ceramics to develop sustainable, lead‐free piezoelectrics. Co‐modification significantly enhances electromechanical coupling and the mechanical quality factor. The optimized KNN‐Ti‐KCT system achieves thermal stability comparable to commercial

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...
