English abstract:
We present numerical simulations of liquid encapsulated Czochralski crystal growth of GaAs under the influence of a travelling magnetic field. As described in Rudolph 2008 (Proceedings for ICCG-15), the magnetic field is generated by an internal heater-magnet module, replacing the usual heater units inside the pressure chamber in the growth arrangement. We consider two possible realizations of the heater-magnet and numerically investigate the influence of the Lorentz force on the melt, e.g., the damping of the temperature oscillations in the Taylor cell below the crystal. This work has been conducted in the project KristMAG framework, see http://www.kristmag.com/, which has been awarded with the Innovationspreis (innovation prize) Berlin-Brandenburg 2008. Figs 8, Refs 10.
