Abstract
The polarization switching kinetics of ferroelectric crystals and the transition from the domain to uniform switching in single-crystal nanofilms have been considered within the Landau–Ginzburg theory. It is shown that, within the chosen theory, the uniform (domainless) switching can be described only for two-dimensional ferroelectrics. Experimental results for two-dimensional films of ferroelectric polymer and barium titanate are presented. For ultrathin polymer films, these results are also confirmed by ab initio calculations.
期刊介绍：
Crystallography Reports is a journal that publishes original articles short communications, and reviews on various aspects of crystallography: diffraction and scattering of X-rays, electrons, and neutrons, determination of crystal structure of inorganic and organic substances, including proteins and other biological substances; UV-VIS and IR spectroscopy; growth, imperfect structure and physical properties of crystals; thin films, liquid crystals, nanomaterials, partially disordered systems, and the methods of studies.
