  • Manipulation of controllable polarization evolutions is a big challenge. The authors fabricate the irregular moirés, identifying three distinct types of moiré domains with different patterns, modulating them by external mechanical force disturbing.

  • Despite enormous efforts by many research groups, Sr2IrO4 was found to stay remarkably insulating in thin film form. Now, a high-pressure oxygen annealing treatment on the Sr2IrO4 thin film realized the long-sought metallicity for the first time. An emerging transport phase diagram was deduced from the experiment that features an interplay between two states: the robust insulating state, which is likely dominated by the defect scattering effect of planar oxygen vacancies O(2), and the new metallic state, which likely reflects an intrinsic bulk-like property of the IrO2 planes with effective electron doping due to apical oxygen vacancies O(1).

  • Whether it is possible to achieve polarization inversion in a ferroelectric without any energy consumption is an open question. Here, the authors demonstrate an energy-free approach to control the polarization state of CuInP2S6, a typical room-temperature van der Waals layered ferroelectric.
