Multiferroic Compounds with Double-Perovskite Structures [PDF]
Materials, 2011 New multiferroic compounds with double-perovskite structures were synthesized. Bi2NiMnO6 was synthesized in bulk form by high-pressure synthesis and also in a thin-film form by epitaxial growth. The material showed both ferromagnetic and ferroelectric properties, i.e., the multiferroic property at low temperature.

Post-perovskite Transition in Anti-structure [PDF]
Scientific Reports, 2016 AbstractThe discovery of the post-perovskite transition, which is the structural transition from the perovskite to post-perovskite structure in MgSiO3 under pressure, has aroused great interests in geosciences. Despite of previous extensive studies, key factors of the post-perovsktie transition are still under hot debate primarily due to the big ...

Processing and characterization of lead-free ceramics on the base of sodium–potassium niobate [PDF]
Journal of Advanced Dielectrics, 2018 Lead-free sodium–potassium niobate-based piezoelectric materials are most intensively studied in order to replace the widely used Pb-based ones. In this work, the effects of modification of compositions by donor and acceptor dopants in the A- and B-sites

Optimizing Cs2TiBr6-Based PSCs with Graphene Quantum Dots
Engineering Proceedings, 2023 The overall efficiency and optimization of perovskite solar cells are significantly influenced by the selective layers in the cells. In this study, particular emphasis is placed on a perovskite solar cell architecture in which the charge transport layer ...

Exciton Fine Structure in Perovskite Nanocrystals [PDF]
Nano Letters, 2019 The bright emission observed in cesium lead halide perovskite nanocrystals (NCs) has recently been explained in terms of a bright exciton ground state [ Becker et al. Nature 2018 , 553 , 189 - 193 ], a claim that would make these materials the first known examples in which the exciton ground state is not an optically forbidden dark exciton.
