| 초록 | There are two reciprocal behaviors of impurity in layer crystallization: one is the inclusion of impurity in growing the crystalline layer and the other is the migration of the impurity inclusion entrapped. The liquid impurity inclusions are trapped in the crystal layer during its growth, and moved simultaneously away from the crystalline layer by the temperature gradient established between the cooled surface of crystallizer and the S-L interface. Eventually, in layer melt crystallization, the concentration of the crystalline layer is decided by both the impurity entrapped in the growing layer and the impurity migrated by the temperature gradient. Migration effect on the movement of impurity inclusions was never considered in the growth of the crystalline layer. This study investigated the effect of inclusion and migration on impurity behavior during the layer growth. |
