Aims of the project: The aim of the proposed project is the research of methods for visualization of ferroelectric domain walls using digital holographic tomography. Within the project, there will be developed, first, methods for optical visualization of static domain walls and, second, methods for visualization of dynamic displacements of domain walls in harmonic external electric field. The developed methods will applied to visualization of static and dynamic phenomena in ferroelectric domain patterns, such as coexistence of more than two domain states in a ferroelectric material, interactions of domain walls with crystal lattice defects, nucleation of domains during processes of polarization switching, etc. Results of optical observations will be used for calibration and verification of numerical models based on phase field modeling. Since domain patterns have tremendous effect on macroscopic properties of ferrorelectric materials, results of the project will be used for the development of characterization tools for the optimization of fabrication technology of ferroelectric materials.
