Novel Complex Nanostructure from Directed Assembly of Block Copolymers on Incommensurate Surface Patterns |
| 초록 |
Hybrid technologies combining top-down and bottom-up fabrication have been developed and have attracted a great deal of technological attention as a next-generation fabrication technique. Block copolymers are representative self-assembling materials extensively utilized in nanofabrication. Various shapes of block copolymer nanostructures can be generated with a precise tunability of shape and size. Here, we demonstrate that the directed assembly of a block copolymer on a chemically patterned surface may produce a well-registered novel complex nanostructure. When a cylinder-forming block copolymer was assembled on a chemical pattern whose period was twice as large as the natural lattice size of the block copolymer, a new structure was produced, where cylinders were oriented alternately perpendicular and parallel to the surface. Our work shows that a judiciously designed chemical pattern may be used to fabricate a well-ordered complex nanostructure in block copolymer thin films. |
