Static structures and dynamic responses of polar topologies in oxide superlattices
نویسندگان
چکیده
Polar topologies in ferroelectric/paraelectric superlattices have been an important substance to explore exotic physical properties. Although enormous efforts paid this field, the universality of formation polar various and their electric field dynamics is still unknown. Herein, we employ a phase-field model construct three types with tetragonal, rhombohedral, orthorhombic symmetries investigate static structures dynamic responses as function epitaxial strain. It found that all undergo similar vortex–spiral–in-plane topology transition, which corresponds peaked dielectric permittivity curves ferroelectric-, antiferroelectric-, paraelectric-like hysteresis loops. Such polarization behaviors are attributed triple-well free energy landscape. The flexibility loops generates high density efficiency superlattices. This study offers systematic view generality multilayered ferroelectrics.

15 صفحه اولStatic and Dynamic Membrane Structures
While originally P systems were defined to contain multiset rewriting rules, it turned out that considering different types of rules may produce important results, such as increasing the computational power of the rules. This paper focuses on factoring out the concept of a membrane structure out of various P system models with the goal of providing useful formalisations. Both static and dynamic...
متن کاملStereotypes: static abstractions or dynamic knowledge structures?
Stereotypes have been assumed to be long-lasting knowledge structures that persist even in the face of contrary evidence. However, there is almost no within-participant research relevant to this assumption. The authors describe 4 studies (N=267), the first 3 of which assessed within-participant stereotype stability over a few weeks with measures of stereotypic trait verification, typicality rat...
