Ferroelectricity and multiferroicity in anti–Ruddlesden–Popper structures [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Ferroelectric materials are of great interest for both applied and fundamental reasons. One of the focuses of the community has been to combine ferroelectricity with other properties such as light absorption or ferromagnetism. Unfortunately, these additional properties have been difficult to add to traditional ferroelectrics such

A brief review of conductivity and thermal expansion of perovskite-related oxides for SOFC cathode
Eurasian Journal of Physics and Functional Materials, 2021 Cathode materials with mixed ion-electron conductivity (MIEC) are necessary for the development of low or intermediate temperature solid oxide fuel cells. Perovskite and perovskite-related materials are promising candidates on this role.

Are Mixed-Halide Ruddlesden-Popper Perovskites Really Mixed? [PDF]
ACS Energy Lett, 2022 Mixing bromine and iodine within lead halide perovskites is a common strategy to tune their optical properties. This comes at the cost of instability, as illumination induces halide segregation and degrades device performances. Hence, understanding the behavior of mixed-halide perovskites is crucial for applications. In 3D perovskites such as MAPb(Br x

Improved control of atomic layering in perovskite-related homologous series
APL Materials, 2021 Homologous series are layered phases that can have a range of stoichiometries depending on an index n. Examples of perovskite-related homologous series include (ABO3)nAO Ruddlesden–Popper phases and (Bi2O2) (An−1BnO3n+1) Aurivillius phases.

Many-Exciton Quantum Dynamics in a Ruddlesden-Popper Tin Iodide. [PDF]
J Phys Chem C Nanomater Interfaces, 2023 We present a study on the many-body exciton interactions in a prototype Ruddlesden-Popper metal halide (RPMH), namely \ce{(PEA)2SnI4} (PEA = phenylethylammine), using coherent two-dimensional electronic spectroscopy. The optical dephasing times of the third-order polarization observed in these systems are determined by exciton many-body interactions ...
