1. An apparatus for crystal growth, comprising:

  • a crystal growth furnace having a heating source and a movable crucible support that supports a crucible having raw material and containing a seed crystal; and

    a controller which is coupled to the crystal growth furnace, the controller controlling the heating source and the movable crucible support to perform a crystal growth process on the crucible when in the furnace wherein the heating source is adjusted to move the crystallizing temperature gradient relative to the crucible which is stationary to melt the raw material and reform it as a monocrystalline compound and to perform, at a predetermined crystal growth length, a crystal growth process on the crucible wherein the crucible is moved relative to the heating source which is stationary to continue to melt the raw material and reform it as a monocrystalline compound.
