Static domain patterns produced by application of the external electric field in wide temperature range in single crystals of congruent, stoichiometric and MgO doped lithium niobate LiNbO3 (LN) and lithium tantalate LiTaO3 (LT) were investigated experimentally in great detail. Moreover the domain kinetics has been studied by computer simulation and experimentally in model structure in order to check applicability of the kinetic approach to explanation of the individual domain shape and domain structure evolution for switching from multidomain initial state [1].The step-by-step kinetic model of the domain growth was realized in the model experiment. Evolution of two-dimensional (2D) domain patterns has been investigated in CLN produced by application of external electric field by 2D electrode grating (Fig. 1). The grating structure has been produced by photolithography and the field has been applied using liquid electrolyte.& more.
