Modeling of InP Crystal Growth by the MLEK Process.

Abstract

The goal of this work is to achieve prototype simulations of the MLEK process for growth of InP crystals. We have made several key advances in this work, including numerical simulations of three dimensional time dependent low Prandtl number melt convection, with differential rotation, and magnetic fields. To do this we have developed a 3D general geometry spectral element code. We have demonstrated how rotation and, especially, differential rotation can stabilize melt flows and how magnetic fields can also stabilize these flows. We have also shown that magnetic fields, in certain parameter regimes, can act, somewhat surprisingly, to destabilize the flow. We have also extended our renormalization group based turbulence models to describe stratified flows across the full range of low, moderate, and high stratification.
