Аннотация: The effect of crystallization front shape on the dislocation density in Ge single crystals with a diameter of 100 mm, grown by the Czochralski method, has been studied. The dislocation density in crystals with a convex crystallization front is found to be considerably higher. The average dislocation density in experimental ingots wПоказать полностьюith deviation of crystallization front shape from flat in the range from -1.5 to +1.5 mm increases from 75 to 1000 cm(-2) and from 75 to 700 cm(-2) in the cases of convex and concave fronts, respectively. Minimum dislocation densities are observed for a flat or slightly concave front.
