Germanium crystals doped by antimony are grown by the Czochralski technique along 12 different crystallographic directions. The effective distribution coefficients ( K ef ) are determined here. It is shown that orientation dependence of k ef could be explained by supercooling at growth surfaces correlating with number of layer systems {111} crossing that surfaces and with angles between that systems and direction of shift of the crystallization front.
