摘      要：The recent achievements in studying the self-assembled evolution of micro-and nanoscale domain structures in uniaxial single crystalline ferroelectrics lithium niobate and lithium tantalate have been *** results obtained by visualization of static domain patterns and kinetics of the domain structure by different methods from common optical microscopy to more sophisticated scanning probe microscopy,scanning electron microscopy and confocal Raman microscopy,have been *** kinetic approach based on various nucleation processes similar to the first-order phase transition was used for explanation of the domain structure evolution *** main mechanisms of self-assembling for nonequilibrium switching conditions caused by screening ineffectiveness including correlated nucleation,domain growth anisotropy,and domain–domain interaction have been *** formation of variety of self-assembled domain patterns such as fractal-type,finger and web structures,broad domain boundaries,and dendrites have been revealed at each of all five stages of domain structure evolution during polarization *** possible applications of self-assembling for micro-and nanodomain engineering were reviewed *** review covers mostly the results published by our research group.
