Lamellae-forming polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) films, with bulk period L0, were directed to assemble on lithographically nanopatterned surfaces. The chemical pattern was comprised of “guiding” stripes of cross-linked pol

We systematically investigated the effect of surfactant addition on the orientational change in polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) block copolymer films as a function of film t...

Ternary blends of cylinder-forming polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) and low molecular weight PS and PMMA were directed to assemble on chemically patterned surfaces with hexagonal symmetry. The chemical patterns consisted of str

A computational procedure is presented to quantify the order achieved in assembled block copolymer films when no disruptive defects are present (i.e., dislocations or disclinations). Both simulated and real systems were used to show that sub-nm varia

Block copolymer structures have been directed to assemble on chemically patterned surfaces with the domain interfaces oriented perpendicular to the substrate. Such methods have been pursued for lithographic applications to achieve long-range order in

We have developed a method of using Ar ion milling and SEM to visualize the cross section of blockcopolymer films that were 50 nm thick. Directed assembly of lamellae-forming PS-b-PMMA on one-to-one and two-to-one chemical patterns was studied by bot

We present a control strategy for the facile placement of densely packed nanomaterial arrays (i.e., nanoparticles and nanorods) on surface reconstructed polystyrene-block-poly(methyl methacrylate) thin film patterns. The surface reconstruction of per

It has been well established that one of most important factors to control the orientation of microdomains in block copolymer (BCP) films is the wetting behavior of a BCP at the interface (or on a substrate). From this perspective, we studied the wet
