摘要

InSb single crystals were grown in the < 111 > direction by a modified Czochralski method. Ultrasonic waves at a frequency of 0.71 MHz were introduced into the melt parallel and perpendicular to the pulling axis at frequencies of 1.25, 1.44, and 2 MHz under the solid-liquid interface. The influence of solid-liquid interface shape on morphology and elimination of striations was found during crystal growth due to the effect of the ultrasound in two orthogonal directions.
