To effectively control dislocations of monocrystalline-like silicon grown in the  and  directions, the relationship between the locations of activated dislocations and the cooling flux direction was studied numerically from the perspective of activation of slip systems. The cooling flux direction was shown to have a significant effect on the activation of slip systems. The radial flux and axial flux activate different slip systems at different locations in the crystal. The relationship between the flux direction and the activation of slip systems in the  and  growth directions has been revealed. The results provide theoretical support for reducing dislocations inside a crystal or in the part of the crystal where dislocations can cause the most damage, by intentionally controlling the flux direction during the crystal growth process.
