Generally, well-tailored control of fluid flow is required for growing crystals with high uniformity of chemical composition. This is of particular importance in the case of layer growth, where both composition and thickness strongly depend on the mass flux of the different components. A typical example is the liquid phase epitaxy (LPE) of (Hg,Cd)Te layers on (Cd,Zn)Te substrates from Hg-Cd-Te melt-solutions. For the first time, we studied the controlled enhancement of mixing for such a system by using travelling magnetic fields (TMFs). Picking up the most promising TMF for experimental runs we observed a remarkable improvement of the homogeneity. (C) 2010 Elsevier B.V. All rights reserved.
