ABSTRACT:
Apparatus and method for growing a crystal from a melt of a growth material, wherein crystal growth occurs at a solid-liquid interface between the melt and the crystal, and a characteristic of the solid-liquid interface is determined by using a float atop the melt and a detector for detecting displacement of the float. The characteristic of the solid-liquid interface can be at least one of the following: position, velocity or acceleration of the solid-liquid interface.
