Similar to PZT and its precursor barium titanate, these typically have an asymmetric perovskite crystal structure in which a large metal ion is systematically displaced from its symmetric position ...

However, their results transcend the specific choice of material and presumably extend to other thin-film oxides, such as barium titanate or its perovskite family. The fundamental physics involved ...

Their findings, published in the journal “Science Advances,” described a lattice arrangement of three different layers of ferroelectric crystals (in this case, of barium titanate, strontium ...
