ROTATIONAL STRIATIONS IN CZOCHRALSKI-GROWN LiNbO3 SINGLE CRYSTALS
直拉法LiNbO3单晶体中的旋转生长条纹

We intentionally render the rotational axis of growing crystal to deviate from the symmetry axis of the temperature field, the temperature fluctuations with sinusoidal form in meniscus are produced. The one-to-one correspondance between speed of crystal revolution temperature fluctuations, surface growth striations and interior growth striations have been demonstrated.
