Ferroelectric materials are distinguished by a spontaneous macroscopic polarisation that can be reversed by an external electric field. These systems undergo phase transitions that are central to ...
Certain two-dimensional (2D) van der Waals-bonded bilayers (e.g., WTe₂ and h-BN) exhibit “sliding ferroelectricity (SF),” where electric polarization arises from specific stacking configurations ...
High-quality relaxor ferroelectric BNT-based ceramics achieved high discharge density by many methods of chemical doping, hierarchical structure design, advanced sintering technology, and defect ...
