摘要: The growth of YAG bulk crystals was studied using both theoretical calculations based on the anisotropic chemical bonding conditions and practical via Czochralski (Cz) method. theory single crystal quantitatively describes behaviors constituent atoms during crystallizing, which can be applied to thermodynamic crystals. Both symmetry determine projection configuration along pulling direction ridges in shoulder grown [111] direction. During Cz process crystals, relative low rate directions results exposure surfaces normal directions. However, energy density at intersection two adjacent is higher, leading truncated-hexagon ϕ 3′′ successfully grown. Our present work provides a promising approach achieve controllable for functional kinetic controls.
