  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 co-polymer templates. To this end we focus on
the experiments conducted by Lopes {\it et al} (Nature, 2001), 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 wire-like states obtained by the evaporation-deposition of silver on the
template. We show the existence of ``non-trivial'' 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.
