Screening-Induced Phase Transitions in Core-Shell Ferroic Nanoparticles
Anna N. Morozovska, Eugene A. Eliseev, Yulian M. Vysochanskii +2
Using the Landau-Ginzburg-Devonshire approach, we study screening-induced phase transitions in core-shell ferroic nanoparticles for three different shapes: an oblate disk, a sphere…
Dynamic control of ferroionic states in ferroelectric nanoparticles
Anna N. Morozovska, Sergei V. Kalinin, Mykola E. Yelisieiev +4
The polar states of uniaxial ferroelectric nanoparticles interacting with a surface system of electronic and ionic charges with a broad distribution of mobilities is explored, whic…
Chiral Polarization Textures Induced by the Flexoelectric Effect in Ferroelectric Nanocylinders
Anna N. Morozovska, Riccardo Hertel, Salia Cherifi-Hertel +3
Polar chiral structures have recently attracted much interest within the scientific community, as they pave the way towards innovative device concepts similar to the developments a…
Flexo-Elastic Control Factors of Domain Morphology in Core-Shell Ferroelectric Nanoparticles: Soft and Rigid Shells
Eugene A. Eliseev, Anna N. Morozovska, Riccardo Hertel +4
Within the framework of the Landau-Ginzburg-Devonshire approach we explore the impact of elastic anisotropy, electrostriction, flexoelectric couplings, and mismatch strain on the d…
Controlling the domain structure of ferroelectric nanoparticles using tunable shells
Anna N. Morozovska, Eugene A. Eliseev, Yevhen M. Fomichov +3
The possibility of controlling the domain structure in spherical nanoparticles of uniaxial and multiaxial ferroelectrics using a shell with tunable dielectric properties is studied…
