The Distribution of Solute in Crystals Grown from the Melt. Part I. Theoretical

The incorporation of solute elements into single crystals of germanium grown from the melt is examined in terms of a simple model. The theory takes account of the contribution of solute transport in the melt, owing to diffusion and fluid motion, to the over-all process of impurity incorporation during steady-state crystallization. The analysis is extended to treat the transient inclusion of solute which results when the composition of the melt is abruptly changed.
