Tunneling‐Controlled Fusion of Short‐ and Long‐Term Memory in SiO2/HfO2‐Based Neuromorphic Device for Time‐Series Prediction

Advanced Science, EarlyView.
Based on trap‐assisted tunneling, the devices can fuse STM/LTM, where the low switching energy of 1 pJ and stable low‐power retention (0.2 % loss ratio and 3.05 × 10−11 W) is achieved. Training in a long short‐term memory network it allows to analysis time‐series data and then makes precise long‐term predictions with an error ratio of 4.465 ...

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Giant Polar Displacements via Strain Relaxation in Itinerant Ferromagnet SrRuO3 Freestanding Films

Advanced Science, EarlyView.
The discovery of substantial Ru off‐centre displacements exceeding 30 pm in SrRuO3 freestanding films is reported, achieved by properly controlling the strain relaxation process to engineer an expanded lattice. The work shows that tailored strain relaxation strategies can be used to design magnetic polar metals with desired electronic states in ...

A Van der Waals Material Exhibiting Room Temperature Broken Inversion Symmetry with Ferroelectricity

Advanced Science, EarlyView.
This study reports a βp$\ubeta^{\text{p}}$ phase of indium selenide showing ferroelectricity over large areas at room temperature in a low‐dimensional limit. It is found that indium selenide films with βp$\ubeta^{\text{p}}$ layers display electric field‐induced switchable polarization characteristic of ferroelectric materials, suggesting the breaking ...
