Abstract:

The formation of self-organized structures of submicron domains under application of the uniform electric field was studied in single crystals of magnesium doped near stoichiometric lithium tantalate grown by double crucible Czochralski method. It was shown that the period of the domain structure (about 1 mu m) appeared on Z(-) polar surface after polarization reversal was almost independent on the electric field. This fact confirms the self-organized nature of the phenomenon. The obtained dependence of the structure geometry on the switching conditions was discussed. The noticeable increase of the low-frequency dielectric permittivity was demonstrated in the samples with charged domain walls.
