METHOD FOR GROWING SINGLE CRYSTAL BY CRYSTALLIZING SINGLE CRYSTAL FROM FLOATING ZONE

摘要

PROBLEM TO BE SOLVED: To provide a method for growing a single crystal by crystallizing the single crystal from a floating zone.SOLUTION: The method includes growing a single crystal by crystallizing the single crystal from a floating zone; the floating zone is induction-heated; the single crystal to be crystallized is rotated in a certain rotational direction; the rotational direction is alternately reversed at a time interval; and a residence time for which the single crystal is in a static state in order to reverse the rotational direction is restricted to 60 milliseconds or less.SELECTED DRAWING: Figure 2
