Abstract

Frontispiece on page 3185: Experiments and self-consistent field calculations reveal the complex structures of nanocylinders with orientations controlled by the underlying surface pattern. The surface pattern has a period of 100 nm, more than twice of the bulk intercylinder distance. As reported on p. 3271 by Sang Ouk Kim, Qiang Wang, and co-workers, judiciously designed surface patterns may be used to fabricate well-ordered complex structures in block copolymer thin films. Directed-assembly techniques therefore provide a versatile pathway to well-registered complex nanostructures, which are useful as template materials in various applications such as plasmonic waveguides or nanowire arrays.
