Layered Double Perovskites [PDF]
Annual Review of Materials Research, 2021 Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX3, perhaps the best-known example of such a family, have a vast range of elements on A, B, and X sites, which are associated with a ...

Free-Carrier-Induced Ferroelectricity in Layered Perovskites [PDF]
Physical Review Letters, 2021 Doping ferroelectrics with carriers is often detrimental to polarization. This makes the design and discovery of metals that undergo a ferroelectric-like transition challenging. In this letter, we show from first principles that the oxygen octahedral rotations in perovskites are often enhanced by electron doping, and this can be used as a means to ...

Layered Perovskites Enhanced Perovskite Photodiodes
The Journal of Physical Chemistry Letters, 2021 Recently, two-dimensional layered perovskites have emerged as effective additives for stabilizing conventional three-dimensional metal halide perovskites. With the addition of layered perovskites, the perovskite-based devices also exhibited enhanced optoelectronic properties, such as reduced nonradiative recombination and ionic migration, strengthened ...

Review of Interface Passivation of Perovskite Layer [PDF]
Nanomaterials, 2021 Perovskite solar cells (PSCs) are the most promising substitute for silicon-based solar cells. However, their power conversion efficiency and stability must be improved. The recombination probability of the photogenerated carriers at each interface in a PSC is much greater than that of the bulk phase.

Templated growth of oriented layered hybrid perovskites on 3D-like perovskites [PDF]
Nature Communications, 2020 AbstractThe manipulation of crystal orientation from the thermodynamic equilibrium states is desired in layered hybrid perovskite films to direct charge transport and enhance the perovskite devices performance. Here we report a templated growth mechanism of layered perovskites from 3D-like perovskites which can be a general design rule to align layered

Self-Hybridized Polaritonic Emission from Layered Perovskites [PDF]
Nano Letters, 2021 Light-matter coupling in excitonic materials has been the subject of intense investigation due to emergence of new excitonic materials. Two-dimensional layered hybrid organic/inorganic perovskites (2D HOIPs) support strongly bound excitons at room-temperatures with some of the highest oscillator strengths and electric loss tangents among the known ...
