PHOTON SCIENCE

Hierarchical self-assembly. Ontop of a nanofaceted substrate a diblock copolymer template is prepared. Metal nanostructures formed during sputter deposition, following the chemical surface patterning presented by the diblock copolymer template. From Sci. Adv. 1, e1500751 (2015).

AFM data illustrating the composition of self-assembled sample systems and the selective wetting of Fe on the copolymer template. Micrograph of a sample system consisting of a sapphire substrate, copolymer template, and Fe nanodots showing the exposed nanofaceted substrate in the upper half and the Fe nanodot array in the lower half. From Sci. Adv. 1, e1500751 (2015).
