Silver niobate based lead-free ceramics with high energy storage density
(Royal Society of Chemistry (RSC), 2019)
<p>Electrical field dependence of permittivity in (1 − <italic>x</italic>)AN-<italic>x</italic>BZN ceramics. Arrow directions down, up and down then up are related to domain switching, field induced transition and domain ...
Phase transitions in bismuth-modified silver niobate ceramics for high power energy storage
(Royal Society of Chemistry (RSC), 2017-07-31)
<p>Ceramics of composition Ag<sub>1−3x</sub>Bi<sub>x</sub>NbO<sub>3</sub> (0.005 ≤ <italic>x</italic> ≤ 0.040) were prepared by solid state methods and their structure and electrical behavior were characterized with a view ...
Ultrafast Electric Field-Induced Phase Transition in Bulk Bi0.5Na0.5TiO3 under High-Intensity Terahertz Irradiation
(American Chemical Society (ACS), 2020-12)
Ultrafast polarization switching is being considered for the next generation of ferroelectric-based devices. Recently, the dynamics of the field-induced transitions associated with this switching have been difficult to ...
High Tunability and Low Loss in Layered Perovskite Dielectrics through Intrinsic Elimination of Oxygen Vacancies
(American Chemical Society (ACS), 2020-11)
Dielectric materials with moderate dielectric permittivity, high tunability, and low loss are critical in modern communication technology. However, high tunability is often associated with high loss and high dielectric ...
Facile one-step synthesis and enhanced photocatalytic activity of WC/ferroelectric nanocomposite
(Royal Society of Chemistry (RSC), 2021-08)
The development of noble-metal-free co-catalysts is seen as a viable strategy for improving the performance of semiconductor photocatalysts. Although the photocatalytic efficiency of ferroelectrics is typically low, it can ...
Structural Evolution in BiNbO4.
(American Chemical Society, 2021-06-01)
The sequence of transitions between different phases of BiNbO4 has been thoroughly investigated and clarified using thermal analysis, high-resolution neutron diffraction, and Raman spectroscopy. The theoretical optical ...
Terahertz Reading of Ferroelectric Domain Wall Dielectric Switching
(American Chemical Society (ACS), 2021-03)
Ferroelectric domain walls (DWs) are important nanoscale interfaces between two domains. It is widely accepted that ferroelectric domain walls work idly at terahertz (THz) frequencies, consequently discouraging efforts to ...
