| Abstract: | The results of experiments on gallium crystal growth under conditions of microturbulent flow in the melt in a nonuniform vibration field are discussed. The vibration field in the conducting melt is generated by superposing profiled constant and oscillating magnetic fields. Among the features of the flow is the onset of intense small-scale turbulent flow which homogenizes the heat and concentration fields in the melt in the neighborhood of the growing crystal. High values of the transport coefficients, in particular, the effective thermal conductivity and diffusion coefficients, which ensure a high degree of supercooling of the melt in the neighborhood of the crystallization front, and a kinetic mechanism of single-crystal growth are recorded. |
