Ultrafast Electric Field-Induced Phase Transition in Bulk Bi0.5Na0.5TiO3 under High-Intensity Terahertz Irradiation
(American Chemical Society (ACS), 2020-12)
Ultrafast polarization switching is being considered for the next generation of ferroelectric-based devices. Recently, the dynamics of the field-induced transitions associated with this switching have been difficult to ...
High Tunability and Low Loss in Layered Perovskite Dielectrics through Intrinsic Elimination of Oxygen Vacancies
(American Chemical Society (ACS), 2020-11)
Dielectric materials with moderate dielectric permittivity, high tunability, and low loss are critical in modern communication technology. However, high tunability is often associated with high loss and high dielectric ...
Low-loss High Entropy Relaxor-like Ferroelectrics with A-site Disorder
(Elsevier BV, 2020-11)
Relaxor ferroelectric ceramics are good candidates for capacitor, sensor and actuator applications because of their high dielectric permittivity, high piezoelectric constant and high value of field induced strain, respectively. ...
Multiscale understanding of electric polarization in poly(vinylidene fluoride)-based ferroelectric polymers
(Royal Society of Chemistry, 2020-01-01)
Poly(vinylidene fluoride) (PVDF) and PVDF-based copolymers with trifluoroethylene (PVDF-TrFE) have attracted considerable academic and industrial interest due to their ferroelectric properties, which are only present in ...
