Abstract

Alignment of perpendicularly oriented lamellar block copolymer domains using an AFM tip is demonstrated. The AFM tip orients the domains through local shearing, resulting in domain alignment parallel to tip travel. AFM tips can also deposit block copolymer nanostructures on heated substrates with a variety of experimentally observed domain alignments.
