TRANSIENT ELECTRICAL-FIELD CHARACTERISTICS DUE TO POLARIZATION OF DOMAINS IN BULK LINBO3 DURING CZOCHRALSKI GROWTH

The transient behavior of the electric field during simultaneous growt h and in situ poling of LiNbO3 has been studied. The transient feature s have been correlated with the poling of the multidomain seed and cry stal, and domain reversal in poled seed. A steady-state condition is o btained after the shoulder region of the crystal is terminated and the crystal reaches its final diameter. Finally, the critical values of f ield parameters necessary to obtain complete monodomain crystals witho ut causing melt electrolysis at the solid-liquid interface have been a nalyzed.
