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 ...

Mathematical modeling of the perovskite and double perovskite crystal structures
Izvestiya Vysshikh Uchebnykh Zavedenii. Materialy Elektronnoi Tekhniki = Materials of Electronics Engineering, 2022 The paper considers the problem of modeling materials with the crystal structure of perovskite and double perovskite. Due to the high complexity of obtaining micro- and nanoscale objects, data on the structure and properties of such materials are especially important.

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.

Chemical Mapping of Excitons in Halide Double Perovskites
Nano Letters, 2023 Halide double perovskites are an emerging class of semiconductors with tremendous chemical and electronic diversity. While their bandstructure features can be understood from frontier-orbital models, chemical intuition for optical excitations remains incomplete. Here, we use \textit{ab initio} many-body perturbation theory within the $GW$ and the Bethe-
