Direct Observation of Electric‐Field‐Driven Phase Transitions Associated with Energy Storage in Antiferroelectric Films

Advanced Science, EarlyView.
The electric‐field‐driven antiferroelectric‐to‐ferroelectric phase transition in epitaxial PbZrO3 films is directly visualized by in situ aberration‐corrected scanning transmission electron microscopy. A sequential transition pathway involving an orthorhombic ferrielectric phase and a monoclinic ferroelectric phase, ultimately stabilizing into a ...

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 ...

Ferroelectric materials for photovoltaics

, 2017
Ferroelectric photovoltaic has been intensively studied during the last years due to possible high efficient charge separation by presence of an internal electric field. Ferroelectric materials show permanent electrical polarization. Ideally, electric contacts would screen the polarization, but if screening is not perfect, it results in the generation ...

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 ...
