Uniform thermomigration utilizing sample movement

摘要

The geometric configuration of a molten zone migrating through a solid body of semiconductor material during thermal gradient zone melting is maintained by noncentro-symmetric rotation of the solid body about an axis displaced therefrom, by centro-symmetric rotation of the solid body, by translation of the solid body, by a combination of centro-symmetric rotation and translation of the solid body or by a combination of noncentro-symmetric rotation and translation of the solid body while being heated by a suitable heat source.
