Evolution of the domain shape during switching in electric field in congruent and stoichiometric lithium tantalate single crystals has been investigated both experimentally and by computer simulation. Domain patterns were observed using optical microscope. It was shown that typical domain shape is triangular for congruent lithium tantalate and hexagonal for stoichiometric one. The domain shape changes during cyclic switching. The kinetic nature of the domain shape has been proposed. The variety of domain shapes from triangular to hexagonal through intermediate shapes has been studied by computer simulation of the isolated domain growth. We report the first evidence of formation of the ordered domain structure in stoichiometric lithium tantalate with artificial dielectric layer. [ABSTRACT FROM AUTHOR] |
