Popis:	Time evolution of the Marangoni flow instability and the effect of oxygen partial pressure on the Marangoni convection were studied. Under the hyper-critical condition (Ma greater than 10,000) the Marangoni flow is almost turbulent. Although the flow instability mode is described by the Wanschura's formula at the low Marangoni number using an aspect ratio of As, such as m = 2/As, flow instability mode shows time dependence at high Marangoni number case. The effect of oxygen on growth striation in silicon crystals grown by the floating-zone method was investigated. 資料番号: AA0046917051
