Flexoelectric Elastomer Enabled by Miscibility‐Driven Succinonitrile Molecular Rotation

Advanced Science, EarlyView.
A flexoelectric material platform is developed by embedding polar plastic crystals into polymer networks. By tuning the microstructure and preserving molecular rotation, strain gradient‐induced polarization is achieved. The resulting elastomer shows scalable and tunable electromechanical output under mechanical deformation, offering a new design route ...

Integration of Freestanding High‐k Oxide Membranes for 2D Ferroelectric Field‐Effect Transistors

Advanced Science, EarlyView.
This work introduces a defect‐tolerant integration strategy that enables freestanding BaTiO3 membranes to form low‐leakage top‐gate junctions with MoS2. The resulting FeFETs exhibit a record 0.22 V nm−1 memory window, ultrahigh‐k response, and near‐ideal subthreshold swings.

High‐Entropy Chemical Composition Design for Ultrahigh Capacitive Energy Storage

Advanced Science, EarlyView.
La‐donor doping suppresses defect charges and reduces domain size via local random fields. Conversely, NaNbO3 addition in BNT‐based ceramics stabilizes the orthorhombic phase. This creates R‐O‐T multiphase polar nanoregions within a cubic matrix, which lowers the energy barrier, delays polarization saturation, and enables a high breakdown strength ...
