Paper Abstract

During preparation for research of processes crystal growth in conditions of space flight are spent investigation main regularity of processes crystal growth CdTe. In result is determined influence of such parameters of process crystal growth, as a way preparations of a material, way seeding and shape of the container, distribution of temperature in the field of a melt and crystal, speed crystal growth. As criterion for assessment of their influence are adopted the geometrical sizes of monocrystals and their structural perfection. Under our assumptions this problem is connected with the structure of liquid, which can be various depending on stoichiometic composition and mode of cooling before crystallization. For stabilization of a structure proposed two-temperature annealing of a polycrystalline load in vapor of Cd. Chosen experimentally conditions of crystal growth has let to increase reproducibility results. Its influence we consider from the point of view of formation of an optimum structure in associated melt, capable to supply optimum conditions crystal growth.
