Outline of Final Research Achievements

This study is aimed at stabilizing the growth of the GaAs single crystal growth. To clarify the complex flow phenomenon of the melt was subjected to modeling by flow observation and numerical simulation of the melt in the crucible that simulates the growth apparatus using a visualization experiment equipment. It was able to clarify the behavior of the complex flow field when the changes of the amount of the melt by visualization experiments. On the other hand, the modeling by numerical simulation, in addition to the modeling of complex flow fields with natural convection was carried modeling of the forced convection due to the rotation. As a result, the model was able to satisfactorily reproduce the flow field by the visualization experiment.In this study, it was possible to clarify the complex flow field and mechanisms of crystal growth associated with it.
