<P>PROBLEM TO BE SOLVED: To provide a method for producing a single crystal and a crucible for single crystal production, sufficiently suppressible of twin defects. <P>SOLUTION: The method for producing a single crystal includes steps of: disposing a seed crystal within the crucible 1; disposing a raw material on the seed crystal within the crucible 1; disposing a sealant on the raw material within the crucible 1; and growing the single crystal on the seed crystal by melting the raw material followed by coagulating. Groove portions 13 are formed on the inner surface of the crucible 1 so as to extend in the depth direction. In the step of disposing the seed crystal, the seed crystal is disposed within the crucible 1 so that the groove portion 13 is located at a facet generating direction of the single crystal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
