SEED SHAFT, SINGLE CRYSTAL PRODUCTION DEVICE, AND SINGLE CRYSTAL PRODUCTION METHOD

摘要

Provided are a seed shaft and a single crystal production device that are capable of suppressing thermal stress on a seed crystal when producing single crystals using the solution growth method. This production device (10) comprises a seed shaft (20). The seed shaft (20) comprises a shaft member (11) and a holding member (13) arranged at the bottom end of the shaft member (11). The holding member (13) comprises a fixed section (15) attached to the seed crystal and a sliding section (14) attached to a lower surface (11a) of the shaft member (11) so as to be capable of sliding along the lower surface (11a).
