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

open access: yesAdvanced Functional Materials, EarlyView.
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 ...

Plasmon mediated cathodic photocurrent generation in sol-gel synthesized doped SrTiO3 nanofilms

open access: yesAPL Materials, 2015
Thin films of SrTiO3 (STO) and Rh-doped SrTiO3 (Rh-STO) were synthesized by sol-gel method and loaded with Ag nanoparticles. Pristine STO films exhibited anodic photocurrent while Rh-STO exhibited cathodic photocurrent.

Coherent Destruction of Photon Emission from a Single Molecule Source

open access: yes, 2004
The behavior of a single molecule driven simultaneously by a laser and by an electric radio frequency field is investigated using a non-Hermitian Hamiltonian approach. Employing the renormalization group method for differential equations we calculate the

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Monte Carlo Simulation of Deffuant opinion dynamics with quality differences

open access: yes, 2004
In this work the consequences of different opinion qualities in the Deffuant model were examined. If these qualities are randomly distributed, no different behavior was observed.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Wirkung des Gemengeanbaus mit Körnerleguminosen sowie der Standraumzuteilung und der Saatstärke auf Kornertrag und Kornproteingehalt von Winterweizen [PDF]

open access: yes, 2005
In stockless organic farms it is difficult to produce winter wheat (Triticum aestivum L.) with high protein content. The objective of this study was to evaluate the effects of intercropping of (i) winter wheat with either winter field bean (Vicia faba L.)

Effect of Atomic Layer Deposition of Ultra‐Thin Oxide on Reactivity and Durability of Perovskite Oxygen Electrodes

open access: yesAdvanced Materials, EarlyView.
This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O
