Czochralski-type crystal growth in transverse magnetic fields

Effect of magnetic field on 3D flow and heat transfer during solidification from a melt

“…Their results are in good agreement with the analytical predictions of Alboussière et al (1996), and Garandet and Alboussiére (1999). In the paper of Witt et al (1970), the effect of lateral horizontal magnetic field on crystal growth appears to be that by on the Czochralski encapsulate. When a uniform static magnetic field is applied to an electrically conducting liquid, liquid motion is reduced because of the Lorentz force yielded by interaction between the imposed magnetic induction and the electric current induced by the magnetic field (Series and Hurle, 1991).…”

Application of differential thermal analysis to investigation of magnetic field effect on solidification of Al–Cu hypereutectic alloy

“…Finally, we should consider the effect of a magnetic field on heat transfer. There were reports [17] showing that a magnetic field increased the effective viscosity of the melt and further led to diminish thermal convection and therefore to decrease heat losses, which delays the growth rates of primary phases as well. Hence, it can be concluded that solute redistribution in the process of growth of primary phases is mainly finished via atom diffusion in present experiments (6 T and 12 T).…”

Research on macro- and microsegregation in semiconductor crystals grown from the melt under the direction of August F. Witt at the Massachusetts Institute of Technology

“…In 1966, Chendzey and Hurle grew Te-doped InSb in a horizontal magnetic field and observed that as the field strength was increased, temperature fluctuations in the melt changed from chaotic to periodic variations, and then to stable and steady values [34]. In 1970, Witt and coworkers [35] applied a horizontal (transverse) magnetic field to Czochralski growth of Te-doped InSb. In addition to near elimination of the socalled non-rotational striations that are associated with turbulent melt convection, they observed an amplification of periodic striations caused by rotation of the crystal in an asymmetric thermal field.…”
