Phase Transitions, Stability, and Dielectric Response of the Domain Structure in Ferroelectric-Ferroelastic Thin Films
Phase Transitions, Stability, and Dielectric Response of the Domain Structure in Ferroelectric-Ferroelastic Thin Films
The first analytical study of phase transitions and domain structure in ferroelastic-ferroelectric epitaxial thin films is presented for an exactly solvable model. The emerging domain structure with domains of equal width (which may be exponentially large) remains stable irrespective of the film thickness. Shifts of the domain walls, unexpectedly, contribute …
