abstract = {Molecular films present an elegant way for the uniform
functionalization or doping of graphene. Here, we present an
in situ study on the initial growth of copper phthalocyanine
(CuPc) on epitaxial graphene on Ir(111). We followed the
growth up to a closed monolayer with low energy electron
microscopy and selected area electron diffraction (μLEED).
The molecules coexist on graphene in a disordered phase
without long-range order and an ordered crystalline phase.
The local topography of the graphene substrate plays an
important role in the nucleation process of the crystalline
phase. Graphene flakes on Ir(111) feature regions that are
under more tensile stress than others. We observe that the
CuPc molecules form ordered domains initially on those
graphene regions that are closest to the fully relaxed
lattice. We attribute this effect to a stronger influence of
the underlying Ir(111) substrate for molecules adsorbed on
those relaxed regions.},
