Meniscus dynamics and melt solidification in the EFG silicon tube growth process

摘要

This paper presents theoretical and numerical study of meniscus dynamics under symmetric and asymmetric configurations. A meniscus dynamics model is developed to consider meniscus shape and its dynamics, heat and mass transfer around the die-top and meniscus, interaction of solidification with meniscus and tube thickness variation. The parametric studies are conducted to reveal the correlations among tube thickness, effective melt height, pull rate, die-top temperature and crystal environmental temperature.
