  • First topic of this paper aims to clarify how oxygen and heat transfer in silicon melt under cusp-shaped magnetic fields. We obtained asymmetric temperature distribution by using time dependent and three-dimensional calculation. Second topic is study on molecular dynamics simulation, which was carried out to estimate diffusion constants of oxygen in silicon melt.

  • Constitutional supercooling due to concentration gradient at solid-liquid interface in the melt can be avioded by increasing rotational speed for growing $LiNbO_3$ single crystals from the stoichiometric melt. Growth conditions for high quality crystals were determined by rotational speed by which other growth parameters were adjusted.
