  • Wafer bonding has allowed the synthesis of twisted interfaces which support polar discontinuities in ferroelectric lithium niobate. Two-dimensional sheet conductivity arises but is suppressed when twist angles lead to interfacial lattice aperiodicity.

  • Ferroelectric superlattices can present a rich variety of phenomena. Here, in PbTiO3/SrRuO3 superlattices, it is shown that a complex and stable hierarchical supercrystal can form, with the correlated metal of the SrRuO3 layers showing large curvatures.

  • Measurements of four different infinite-layer nickelates show that magnetic behaviour coexists with superconductivity. This is different from what is seen in cuprates, giving a strong distinction between the two classes of oxide superconductors.

  • Negative capacitance is observed in a model system of multidomain ferroelectric–dielectric superlattices; the multidomain state can increase the temperature range over which negative capacitance can be observed.
