  • Neuromorphic computing hardware normally makes an unideal trade-off between energy efficiency, scalability and reliability. Kim et al. report a ferroelectric heterostructure based memristor with near-zero nonlinearity, endurance beyond 10E7 cycles, rectifying ratio exceeding 10E6 and sub-pA off-current.

  • Ferroelectric materials are characterized by a spontaneous polarization, which in practical applications is manipulated by an electric field. This study examines how defects affect the switching with atomic resolution, by usingin situaberration-corrected transmission electron microscopy.

  • Single-electron transistors are written at the heterointerface of two oxides using an atomic force microscope tip, and the electrons in the device can be controlled by gating and the ferroelectric state of the heterostructure.

  • Researchers report rewritable nanoscale photodetectors that exploit 2–3 nm nanowire junctions. Large electromagnetic fields in the gap region aid the detector response, which is electric-field-tunable and spans the visible to near-infrared regime.

  • The interface between complex oxides can show effects such as superconductivity or magnetism that can be controlled through parameters such as carrier density. Here, the authors use magnetic force microscopy to study the magnetism at the interface between LaAlO3/SrTiO3and its dependency on charge carriers.

  • Three-dimensional nanocup Bi3.25La0.75Ti3O12–CoFe2O4 heterostructure film is obtained via a heavily Co, Fe co-doped ferroelectric Bi3.25La0.75Ti3O12 target during pulsed laser deposition. The unique 3D nanocup architecture beyond usual architectures enables reversible magnetoelectric switching of the multiferroic heterostructure film through overcoming leakage issues, as well as efficient interfacial strain coupling based on their structural benefits.

  • We provide a conclusive demonstration of strain-induced room-temperature ferroelectricity in SrMnO3 thin films by securing samples with insulating properties and clean surfaces using selective oxygen annealing. These findings will not only provide a cornerstone for exploring the physical properties of multiferroic SrMnO3 but will also inspire new directions for single-phase multiferroics.
