Formation and rapid evolution of domain structure at phase transitions in slightly inhomogeneous ferroelectrics and ferroelastics
A. M. Bratkovsky, A. P. Levanyuk
We present the analytical study of stability loss and evolution of domain structure in inhomogeneous ferroelectric and ferroelastic samples for exactly solvable models. The model a…
Formation and rapid evolution of domain structure at phase transitions in slightly inhomogeneous ferroelectrics
A. M. Bratkovsky, A. P. Levanyuk
We present the first analytical study of stability loss and evolution of domain structure in inhomogeneous ferroelectric samples for exactly solvable model. The model assumes a sho…
Proper ferroelastic phase transitions in thin epitaxial films with symmetry-conserving and symmetry-breaking misfit strains
A. M. Bratkovsky, A. P. Levanyuk
We study how the ferroelastic domain structure sets in in an epitaxial film of a material with second order proper ferroelastic transition. The domain structures considered are sim…
Rigidity of the elastic domain structure near the boundary of its existence in thin epitaxial films
A. M. Bratkovsky, A. P. Levanyuk
We consider an interesting and practically important case of elastic domain structure, which is the analogue of c/a domain pattern with 90 walls in perovskites, and is solv…
Very large dielectric response of thin ferroelectric films with the dead layers
A. M. Bratkovsky, A. P. Levanyuk
We study the dielectric response of ferroelectric (FE) thin films with "dead" dielectric layer at the interface with electrodes. The domain structure inevitably forms in the FE fil…
Phase transitions, stability, and dielectric response of the domain structure in ferroelectric-ferroelastic thin films
A. M. Bratkovsky, A. P. Levanyuk
We present the first analytical study of phase transitions in ferroelastic-ferroelectric epitaxial thin films on exactly solvable model. The emerging domain structure with domains…
Abrupt appearance of the domain pattern and fatigue of thin ferroelectric films
A. M. Bratkovsky, A. P. Levanyuk
We study the domain structure in ferroelectric thin films with a `passive' layer (material with damaged ferroelectric properties) at the interface between the film and electrodes w…
