Shape Evolution of Isolated Micro-Domains in Lithium Niobate

The varieties of domain shapes produced in single crystals of lithium niobate LiNbO 3 family by application of the uniform electric field have been revealed. The crucial role of predetermined nucleation effect representing the step generation at vertices of polygon domain and step growth in three Y directions was discussed. We put emphasis on formation of unusual domain shapes created by switching in non-equilibrium conditions arisen due to retardation of the screening of depolarization field. Formation of oriented fingers and dendrite self-assembled domain structures during switching with artificial surface dielectric layer and during spontaneous backswitching was considered.
