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-

Halide Double-Perovskite Semiconductors beyond Photovoltaics [PDF]

ACS Energy Letters, 2022
Halide double perovskites, A2MIMIIIX6, offer a vast chemical space for obtaining unexplored materials with exciting properties for a wide range of applications. The photovoltaic performance of halide double perovskites has been limited due to the large and/or indirect bandgap of the presently known materials.
