Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides [PDF]

Angewandte Chemie International Edition, 2021
AbstractControl of cation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O6 double double perovskites, where both A and B sites have 1:1 cation order, to (A0.5A′0.5)2BB′O6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in

Layered Double Perovskites [PDF]

Annual Review of Materials Research, 2021
Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX3, perhaps the best-known example of such a family, have a vast range of elements on A, B, and X sites, which are associated with a ...

CaFeFeNbO₆ – an iron-based double double perovskite [PDF]

Chemical Communications, 2023
CaFeFeNbO6, synthesised at 14 GPa pressure, is the first reported Fe-based double double perovskite. Fe/Nb disorder leads to a spin glass ground state below a freezing transition at 12 K.

Double and double double perovskites in the RMnMnTaO6 series [PDF]

Journal of Solid State Chemistry, 2022
A new family of perovskites RMnMnTaO6 has been synthesised at high pressure for representative R ​= ​La, Nd, Sm, Eu, Gd, Y and Lu that span the whole rare earth series. The structure type changes from tetragonal P42/n double double perovskite (DDPv) type with columnar R3+/Mn2+ cation order (R ​= ​La, Nd, Sm) to monoclinic P21/n double perovskite (DPv) (

Two-Dimensional Halide Pb-Perovskite–Double Perovskite Epitaxial Heterostructures

Journal of the American Chemical Society, 2023
Epitaxial heterostructures of two-dimensional (2D) halide perovskites offer a new platform for studying intriguing structural, optical, and electronic properties. However, difficulties with the stability of Pb- and Sn-based heterostructures have repeatedly slowed the progress.

Halide Double Perovskite Ferroelectrics

Angewandte Chemie, 2020
AbstractHalide double perovskites have recently emerged as a promising environmentally friendly optoelectronic and photovoltaic material for their inherent thermodynamic stability, high defect tolerance, and appropriate band gaps. However, to date, no ferroelectric material based on halide double perovskites has been discovered.

Machine learning bandgaps of double perovskites [PDF]

Scientific Reports, 2016
AbstractThe ability to make rapid and accurate predictions on bandgaps of double perovskites is of much practical interest for a range of applications. While quantum mechanical computations for high-fidelity bandgaps are enormously computation-time intensive and thus impractical in high throughput studies, informatics-based statistical learning ...
