2 TWO-DIMENSIONAL QUASI CRYSTAL STRUCTURE

摘要

Forming a first layer of material comprising a polygonal crystal structure on a substrate; Heat treating the first material layer to convert into a second material layer having the same crystal structure as the polygonal crystal structure; And growing a third material layer having the same crystal structure as the polygonal crystal structure on the substrate, wherein the polygonal crystal structure of the second material layer and the polygonal crystal structure of the third material layer are different from each other Dimensional quasicrystalline structure with directionality and being staggered and laminated.
