Abstract

This paper presents one part of a concerted effort to understand the solidification and crystal growth of semiconductor materials using the bottom-seeded growth technique with externally applied electric and magnetic fields. A physics-based model is developed to study the gravitational (convection), thermoelectric (Peltier, Seebeck, Joule and Thomson) and magnetohydrodynamic (Lorentz force) effects on solidification phenomena. Several combinations of the magnitudes and directions of the two fields are studied. The calculated effects of the applied electrical and magnetic fields on the thermal distribution and position and shape of the solidification front are presented for bottom-seeded GaSb growth.
