Abstract

Studies aimed at determining the degree of inhomogeneity in the distribution of a doping impurity with a distribution coefficient in excess of unity were carried out on Ge single crystals doped with Si and grown in three ways: stationary method by slow cooling, pulling by Czochralski's method, and pulling from a melt supplied with a solid ingot. In specimens grown by the stationary method of slow cooling at a cooling rate of 1.5 deg/hr, the ingots were found to be inhomogeneous along the length and cross section. A homogeneous ingot structure was obtained by using the method of supplying the melt. (Author), Edited machine trans. of Akademiya Nauk Gruzinskoi SSR, Tiflis. Institut Metallurgii.
