Ruddlesden-Popper Phase in Two-Dimensional Inorganic Halide Perovskites: A Plausible Model and the Supporting Observations.
A Ruddlesden-Popper (RP) type structure is well-known in oxide perovskites and is related to many interesting properties such as superconductivity and ferroelectricity. However, the RP phase has not yet been discovered in inorganic halide perovskites. Here, we report the direct observation of unusual structure in two-dimensional CsPbBr3 nanosheets which could be interpreted as the RP phase base...
متن کاملControlling Oxygen Mobility in Ruddlesden–Popper Oxides
Discovering new energy materials is a key step toward satisfying the needs for next-generation energy conversion and storage devices. Among the various types of oxides, Ruddlesden-Popper (RP) oxides (A₂BO₄) are promising candidates for electrochemical energy devices, such as solid oxide fuel cells, owing to their attractive physicochemical properties, including the anisotropic nature of oxygen ...
متن کاملImpact of octahedral rotations on Ruddlesden–Popper phases of antiferrodistortive perovskites
This work presents the most detailed and extensive theoretical study to date of the structural configurations of Ruddlesden–Popper (RP) phases in antiferrodistortive (AFD) perovskites and formulates a program of study which can be pursued for RP phases of any AFD perovskite system. We systematically investigate the effects of oxygen octahedral rotations on the energies of RP phases in AFD perov...
متن کاملAtomic scale imaging of competing polar states in a Ruddlesden–Popper layered oxide
Layered complex oxides offer an unusually rich materials platform for emergent phenomena through many built-in design knobs such as varied topologies, chemical ordering schemes and geometric tuning of the structure. A multitude of polar phases are predicted to compete in Ruddlesden-Popper (RP), An+1BnO3n+1, thin films by tuning layer dimension (n) and strain; however, direct atomic-scale eviden...
متن کاملSynthesis and photocatalytic activity of K2CaNaNb3O10, a new Ruddlesden-Popper phase layered perovskite.
A new three-layer perovskite oxide with the Ruddlesden-Popper (R-P) phase, K2CaNaNb3O10, and its protonated form were synthesised and their photocatalytic performance was compared to that of KCa2Nb3O10 or the protonated form with the Dion-Jacobson (D-J) structure in terms of H2 and O2 evolution. K2CaNaNb3O10 exhibited a higher activity for O2 evolution than KCa2Nb3O10 when IO3- was used as an e...
