  • Analysis of the mechanical properties of two-dimensional materials is important for device development. Here, the authors report a microscopic method for measuring the adhesion of graphene on top of highly ordered pyrolytic graphite, which exploits atomic-scale blisters formed upon neon atom intercalation.

  • Mixed ceramics and thin films of well-known ferroelectric and antiferroelectric materials reveal dipolar skyrmions, providing a scalable platform to explore the properties and applications of non-collinear polarization textures.

  • Charged domain walls in ferroelectric thin films can be manipulated at the nanoscale and used to induce charges in the surrounding insulating material.

  • Graphene can exhibit pronounced frictional anisotropy, which was thought to arise because of nanoscale ripples. Here, the authors provide evidence that this effect could instead be a result of adsorbates that self-assemble into a highly regular superlattice of stripes with a period of four to six nanometres.

  • Conducting charged ferroelectric domain walls, as potential building blocks for future electronic devices, are unstable and uncommon in ferroelectric materials. Here, Tselev et al. show that neutral insulating domain walls in PbZrO3 and BiFeO3thin films are conductive under microwave excitation, allowing for non-destructive read-out.

  • The atomic displacements that generate ferroelectricity in materials commonly fit a double-well potential energy surface. Here, ferroelectricity in two-dimensional CuInP2S6 is shown to fit a quadruple well due to the van der Waals gap between layers of this material.

  • Domain walls in van der Waals layered ferrielectric CuInP2Se6 exhibit piezoelectric response. This striking departure from traditional ferroelectric behavior is ascribed to a partially polarized antiferroelectric state, where the domain wall separates coexisting regions of ferrielectric and antiferroelectric phases.

  • The controlled creation of one-dimensional conductive channels at the cores of topological defects in the multiferroic material BiFeO3 demonstrates that such defects can drive metal–insulator phase transitions, and might provide a route towards high-density information storage.

  • Understanding the conductivity at the nominally uncharged domain walls in ferroelectrics is still far from complete. Here the authors report an enhanced conduction at domain walls in an ultra-thin (001) BiFeO3 film resulting from the formation of a field-induced meta-stable twisted domain nucleus.
