  • The authors present crackling noise microscopy, a method for measurement of the crackling of individual nanoscale features based on AFM nanoindentation. They use it to investigate crackling noise and avalanches in the domains and domain walls of ferroelectric materials.

  • The use of ferroelectric materials in memory device applications is held back by low retention times. Here, the authors demonstrate that by intentionally introducing defective nanoregions which increase the activation field for domain wall motion, retention times larger than a year can be achieved.

  • Strong correlation between the local strain state and the electronic properties at orthorhombic–rhombohedral (O-R) phase boundaries in mixed-phase BFO thin films leads to electronic conductivity at these boundaries. This rather unusual electrical feature might find applications in nanotechnology.

  • Organic–inorganic metal halide perovskite solar cells have been under the spotlight but what happens in the working solar cell device at the nanoscale remains elusive. Here Kim et al. show that light and voltage bias can induce strain and structural variation which may cause J–V scan hysteresis.

  • Topological structures have considerable potential in nanoelectronics and new device concepts. They are key to the design and understanding of novel functionalities in ferroic materials — that is, materials that have one or more types of built-in order such as magnetic, ferroelectric, ferroelastic and multiferroic materials.

  • van der Waals ferroelectrics are different from conventional oxide or polymer-based ferroelectrics in terms of both crystal structure and functionality. This Review discusses the experimentally verified van der Waals ferroelectrics, their unique characteristics and their potential applications in post-Moore’s law electronics.
