Object of investigation - the dopant striations, which appear in growing semiconductors single crystals, aim of investigation - the develop of the striations decrease method in growing InSb single crystals Te doping by Czochralski method. Methods of investigation: the modified Czochralski method, the method of chemical etching, the optical and electronic microscope, "light cut" method. Theoretical and practical results: The method growing semiconductor in ultrasonic field was developed. The introduction of ultrasonics at a frequency from 0.6 to 5 MHz decreases the striations in the facet. Degree of inculcation: The proposal method of crystal growth used for growing GaAs and Bi-Sb single crystals. Field of application: technology of semiconductors materials.
