Study on the Free-Surface Flow of Silicon Melt in the Crucible

摘要

The flowing of the free-surface-layer melt in the crucible has been studied by means of observing the movement ofthe mark particle on the free-surface of silicon melt.A new view on the transportation of the impurities in the melt hasbeen presented.The experimental results verify the effect of the free-surface-layer mew’s flow on the distribution of theimpurities in the as-grown crystal.
