Abstract:
1. A structure, comprising: a substrate; a surface layer on and in direct mechanical contact with the substrate, said surface layer configured to induce a block copolymer to form line-forming microdomains, said surface layer having at least one trough integrally disposed thereon, said at least one trough comprising a planar first sidewall and a planar second sidewall opposite said first sidewall, wherein said first sidewall and said second sidewall are normal to said surface layer, said first and said second sidewalls being separated by a distance corresponding to a width of a bottom surface of said at least one trough; a plurality of oriented inorganic structures; disposed inside said at least one trough, each structure of said plurality of inorganic structures oriented normal to said first sidewall and said second sidewall; and a block copolymer film disposed in said at least one trough, wherein said block copolymer comprises a first block comprising a first polymer and a second block comprising a second polymer, said first block being covalently bonded to the second block to form a repeating unit of the block copolymer, said first and second polymers being different, wherein line-forming microdomains of said block copolymer are aligned parallel to said first and second sidewalls and normal to said plurality of oriented inorganic structures.
