摘要: In a method and an apparatus for producing monocrystals, in particular of gallium arsenide monocrystals, the crystal growth is carried out with a thermal shock resistant nucleus which is freely standing within a nucleus channel and the interspace in the nucleus channel between the nucleus and the crucible is filled with liquid boric oxide.

摘要: A rotational directional solidification crystal growth system includes a vertical furnace, a crucible, and a rotate support device. The vertical furnace contains a high-temperature portion and a low-temperature portion. The crucible has a seed well and a growth region. The seed well and the growth region contain a seed crystal and raw material, respectively. The crucible moves from the high-temperature portion of the furnace to the low-temperature portion of the furnace or the thermal profile moves related to a stationary crucible to proceed the crystal growth. The rotation support device supports and rotates the crucible, and the tangent velocity of the rotated crucible is no less than about 5&pgr;/3 cm/s.

摘要: A process is disclosed for producing an oxide single crystal, including the steps of: melting a raw material for a single crystal of an oxide inside a crucible, contacting a seed crystal with the resulting melt, growing the oxide single crystal by pulling-down the melt through an opening of the crucible in a given pulling-down axis, and fixedly holding the seed crystal and then reducing an angle of a given crystalline orientation of the seed crystal selected for growing the single crystal to the pulling-down axis.
