Single crystals of Te and Te-Se alloy have been grown under macro-gravity up to 10  g0 by the modified Bridgeman method. The electroresistance and the Hall effect as well as their variations along the sample length were studied at 1.2-300 K. Some influence of the overload level on the distribution of crystal defects and impurities is observed. The effect is due to anomaly of the liquid tellurium density near the solidification point.
