Abstract

The thermoelastic stresses that appear during crystallization have been theoretically estimated for single crystals of germanium grown in the shape of a disk. It is shown that there is a correlation between the stress distribution and the dislocation structure of large single crystals of germanium obtained by the Stepanov method and by directed crystallization.
