Brillouin Light Scattering of Halide Double Perovskite

Advanced Photonics Research, 2022
Cs2Ag1−x Na x In1−y Bi y Cl6 with high photoluminescence quantum yield (PLQY) and broadband emission due to self‐trapped excitons (STEs) is one of the promising candidates for single‐emitter‐based white light–emitting materials and devices.

Halide Double-Perovskite Semiconductors beyond Photovoltaics

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.

Thermochromic Lead‐Free Halide Double Perovskites [PDF]

Advanced Functional Materials, 2019
AbstractLead‐free halide double perovskites with diverse electronic structures and optical responses, as well as superior material stability show great promise for a range of optoelectronic applications. However, their large bandgaps limit their applications in the visible light range such as solar cells.

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-

Tuning Defects in a Halide Double Perovskite with Pressure

Journal of the American Chemical Society, 2022
Dopant defects in semiconductors can trap charge carriers or ionize to produce charge carriers─playing a critical role in electronic transport. Halide perovskites are a technologically important semiconductor family with a large pressure response.

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.

Hybrid Layered Double Perovskite Halides of Transition Metals

Journal of the American Chemical Society, 2022
Hybrid layered double perovskite (HLDP) halides comprise hexacoordinated 1+ and 3+ metals in the octahedral sites within a perovskite layer and organic amine cations between the layers. Progress on such materials has hitherto been limited to compounds containing main group 3+ ions isoelectronic with PbII (such as SbIII and BiIII). Here, we report eight
