Chemical Mapping of Excitons in Halide Double Perovskites. [PDF]

Nano Lett, 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-

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
