Abstract
Disclosed is a method for reproducibly producing large size, single crystals in a crystal growth chamber. The method includes the steps of: (a) forming a plurality of smaller size tiles of single crystals of substantially the same crystal orientation as the desired large size, single crystal; (b) assembling the plurality of smaller tiles into a structure having a larger size while minimizing gapping between adjacent tiles; (c) placing the assembly of smaller tiles formed in step (b) into a growth chamber; and (d) through a growth reaction carried out in the growth chamber, forming a large size single crystal using the assembly of smaller tiles formed in step (b) as a seed crystal for the growth reaction.

A method for reproducibly producing a large size, single crystal in a crystal growth chamber comprising the steps of:
- (a) forming a plurality of smaller size tiles of single crystals of substantially the same crystal orientation;
- (b) assembling the plurality of smaller tiles into a structure having a lager size while minimizing gapping between adjacent tiles;
- (c) placing the assembly of smaller tiles formed in step (b) into a growth chamber;
- and
- (d) through a growth reaction carried out in the growth chamber, forming the large size, single crystal using the assembly of smaller tiles formed in step (b) as a seed crystal for the growth reaction.
