Abstract

CdTe and CdTe 0.9Se 0.1 crystals were grown by the travelling heater method under material transport regimes. The different transport regimes in the liquid zone were either caused by diffusion (and residual convection), or by 1 g convection, or by forced convection. The forced convection was produced by a B = 2 mT rotating magnetic field (400 Hz) under μ g conditions. The equations for describing the model of the rotating magnetic field are derived, showing that the magnetic force term in the Navier-Stokes equation can be calculated separately in the case of μ g conditions and small magnetic field. The rotating magnetic field generates a stable steady flow in the solution zone, which improves the radial and axial distribution of μτ products.
