title: Controlled orientation of block copolymers on defect-free faceted surfaces.
abstract: The effect of a faceted surface geometry on controlling the direction of well-defined line patterns of block copolymer (BCP) microdomains over macroscopic areas is reported. Facets with asymmetric base angles can control the direction of BCP microdomains oriented either parallel or perpendicular to the facets depending on BCP film thickness.
