Hybrid Ferroelectric Tunnel Junctions with Intrinsic Nonlinearity and Self‐Rectification via Interfacial Reconstruction

Advanced Functional Materials, EarlyView.
Rapid thermal annealing reconstructs the BCFO/Nb:STO interface into an atomically thin reconstructed interfacial layer, which reshapes the tunneling barrier and converts a high‐TER ferroelectric tunnel junction into an intrinsically nonlinear, self‐rectifying device.

Double perovskites with 3d and 4d/5d transition metals: compounds with promises

Materials Research Express, 2020
Double perovskites, which can host two different transition metal cations at the B-sites of its perovskite derived structure, provide the possibility to explore the interplay of localized 3d transition metals and the relatively delocalized 4d or 5d ...

MAGNETIC AND TRANSPORT PROPERTIES OF DOUBLE PEROVSKITES

Studia Universitatis Babes-Bolyai Chemia, 2021
The magnetic and transport properties of polycrystalline Sr2FeMoO6 perovskites are strongly dependent on their microstructure. A cluster glass type behavior was shown at the grain boundaries.

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays

Advanced Functional Materials, EarlyView.
A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...

Tin‐Based Chiral Perovskites with Second‐Order Nonlinear Optical Properties

Advanced Photonics Research, 2021
Metal halide perovskites have attracted extensive attention as the most favorable candidate for nonlinear optical (NLO) effects, due to their superior infrared transparency, flexible structures, and high laser‐induced damage thresholds.

Theory of transition temperature of magnetic double perovskites [PDF]

Physical Review B, 2001
We formulate a theory of double perovskite coumpounds such as Sr$_2$FeReO$_6$ and Sr$_2$FeMoO$_6$ which have attracted recent attention for their possible uses as spin valves and sources of spin polarized electrons. We solve the theory in the dynamical mean field approximation to find the magnetic transition temperature $T_c$.

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

Advanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Electronic structure of ordered double perovskite Ba2CoWO6 [PDF]

AIP Conference Proceedings, 2014
Ba2CoWO6 (BCoW) has been synthesized in polycrystalline form by solid state reaction at 1200C. Structural characterization of the compound was done through X-ray diffraction (XRD) followed by Rietveld analysis of the XRD pattern. The crystal structure is cubic, space group Fm-3m (No 225) with the lattice parameter, a=8.210A.
