ABSTRACT:
An apparatus includes a sealed vessel, a crucible received in the sealed vessel to hold a first molten liquid of III-V compound semiconductive material and a second molten liquid of an encapsulating material overlying the first molten liquid, and floating member having an opening for defining the cross sectional outline of a single crystal while being grown and positioned in the interface between the first and second molten liquids. The floating member is made from a mixed material consisting essentially of at least one of oxides of yttrium and the lanthanum series elements, alumina and silicon nitride each in a prescribed amount.
