The method also includes forming a solid crystal on the alignment structure. Crystal molecules of the solid crystal are aligned in the predetermined alignment pattern.
Claims20
A method, comprising:
- providing an alignment structure at least partially defining a predetermined alignment pattern;
- and
- forming a solid crystal on the alignment structure, crystal molecules of the solid crystal being aligned in the predetermined alignment pattern.
A method, comprising:
- generating a solid crystal vapor in a chamber based on a source material;
- transporting the solid crystal vapor within the chamber to deposit onto an alignment structure to form a solid crystal material layer;
- and
- crystallizing the solid crystal material layer to form a solid crystal layer.
1 more element
A method, comprising:
- providing a molten crystal material in contact with an alignment structure;
- and
- producing a solid crystal based on the molten crystal material, wherein the solid crystal includes crystal molecules that are aligned in a predetermined alignment pattern at least partially defined by the alignment structure.
