Two/Quasi-two-dimensional perovskite-based heterostructures: construction, properties and applications

International Journal of Extreme Manufacturing, 2023
Two-dimensional (2D)/quasi-2D organic-inorganic halide perovskites are regarded as naturally formed multiple quantum wells with inorganic layers isolated by long organic chains, which exhibit layered structure, large exciton binding energy, strong ...

Oxygen Ion and Proton Transport in Alkali-Earth Doped Layered Perovskites Based on BaLa₂In₂O₇

Inorganics, 2022
Inorganic materials with layered perovskite structures have a wide range of physical and chemical properties. Layered perovskites based on BaLanInnO3n+1 (n = 1, 2) were recently investigated as protonic conductors. This work focused on the oxygen ion and

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

Proton conduction in layered perovskite oxides

, 1994
Investigation of the electrical conductivity behavior of layered perovskite oxides, H2Ln2Ti3O10 (Ln = La, Nd, Sm and Gd), has revealed that the materials exhibit moderate conductivity ( ~10-5 ohms-1 cm-1 at 400°C) in hydrogen atmosphere, that is ...
