title: Kinetic self-assembly of metals on copolymer templates.
abstract: In this work, we seek to understand some of the fundamental processes that govern self-assembly at the nanoscale in the context of the formation of metallic structures on patterned copolymer templates. To this end, we focus on recent experiments where morphologies resulting from the evaporation-deposition of different metals on PS- b -PMMA phase-separated templates were studied. We show that the different morphologies obtained can be understood in terms of the relative importance of the energetics and kinetics. We then focus on a particular morphology: micron-long wirelike states obtained by the evaporation deposition of silver on the template. We show the existence of "nontrivial" correlations between adjacent wires that can be understood based on a purely kinetic mechanism. We also compare these correlations quantitatively to those obtained from simulations done with the relevant experimental parameters and find them in good agreement.
