Abstract

A Floating-Zone method is one of the promising method for producing a silicon single crystal. However, this production method has a problem that it is difficult to increase the size of the crystal. The reason is that it is difficult to maintain the crystal shape under the gravity environment. In addition, defect fringes are generated due to the influence of surface tension (Marangoni) convection, which is an obstacle to high purification of the crystal. Therefore, elucidation of Marangoni convection is very important. In this analysis, in order to introduce the analysis method of gas-liquid two-phase flow on Marangoni convection, we conducted research using a more fundamental model.
