  • Recently, negative pressure has been observed in perovskite nanowires by annealing the wires from a lower-density phase. Here, the authors show that the negative pressure enhances the piezoelectric coefficient of PbTiO3 and Pb(Zr,Ti)O3 nanowires experimentally and by ab initiocalculations.

  • The piezoelectric materials most commonly used for technological applications contain lead, a toxic element. Slukaet al. identify a mechanism that leads to an enhancement of the dielectric and piezoelectric properties of non-toxic ferroelectrics, due to the presence of charged domain walls.

  • Although ferroelectrics are generally insulating, their domain walls can show electrical conductivity. Here Sluka et al. observe a highly conducting free-electron gas at charged domain walls in ferroelectric BaTiO3.

  • In ferroelectrics, the domain walls can have different properties than the domains themselves. Here, Wei et al.show that certain domain walls in antiferroelectric materials are ferroelectric, which makes them interesting candidates for new non-volatile memory concepts.

  • It is shown that a phase change to a denser crystal structure in PbTiO3 nanowires creates a negative-pressure stress state, which is effective in enhancing ferroelectric performance.

  • In magnets and ferroelectrics, domains of regions with different ferroic orientation play an important role for the performance of devices based on these materials. Here, the authors create and control ultrafine domains in a ferroelectric that are only 10 nm wide and extend for tens of micrometres.
