Abstract:
... Dion–Jacobson compounds have a layered perovskite structure, and a small number of them have been identified as being ferroelectric. Here, RbBiNb₂O₇ powders are made by conventional solid-state synthesis. The relatively large Rb ion produces an interlayer within the structure with a large spacing and weak bonding. This work shows for the first time that a polar layered perovskite can be exfoliated ...
