Title: The formation of a dislocation structure in ribbon-shaped germanium single crystals under thermal stress
Abstract: The formation of the dislocation structure in germanium single crystal ribbons grown from melt by Stepanov's method has been studied. It is shown that the relatively high dislocation density in the ribbons is due to thermal stresses present during growth and that the dislocation density can be controlled by properly varying the temperature of a radiation shield. Data are presented on the temperature distribution along the ribbon pulling axis, the tangential thermoelastic stress pattern, and the distribution of dislocations for three different shield geometries. The distribution of dislocations over the ribbon width is shown to correlate well with that of the rms tangential stresses. Samples of low dislocation density germanium ribbon were produced.
