摘要：

Czochralski growth of oxide single crystal was modified using crystal and melt of n-icosane (C20H42) and convective phenomena in the melt and crystal-melt interface shape were observed. Increasing the crystal rotation rate, crystal-melt interface shape changed from convex to flat and from flat to concave toward the melt. Crystal-melt interface shape was independent of melt depth. In order to clarify the effect of convective phenomena on crystal-melt interface shape, a scaling analysis was carried out and applied to experimental results; it can be suggested that the Marangoni convection is dominant in the melt for this system.
