      abstract     = {This paper reports on the formation of large area, self
                      assembled, highly ordered monolayers of stearyl alcohol
                      grafted silica nanospheres of ≈50 nm diameter on a silicon
                      substrate based on the drop-casting method. Our novel
                      approach to achieve improved order uses stearyl alcohol as
                      an assistant by adding it to the colloidal NanoParticle (NP)
                      dispersion from which the monolayers are formed.
                      Additionally, a heat treatment step is added, to melt the
                      stearyl alcohol in the monolayer and thereby give the
                      particles more time to further self-assemble, leading to
                      additional improvement in the monolayer quality. The
                      formation of the monolayers is significantly affected by the
                      concentration of the NPs and the stearyl alcohol, the volume
                      of the drop as well as the time of the heat treatment. A
                      high surface coverage and uniform monolayer film of SiO2 NPs
                      is achieved by appropriate control of the above-mentioned
                      preparation parameters. Structural characterization of the
                      obtained SiO2 NP monolayer was done locally by Scanning
                      Electron Microscopy (SEM), and globally by X-ray
                      reflectivity (XRR) and grazing incidence small-angle X-ray
                      scattering (GISAXS), where the data was reproduced by
                      simulation within the Distorted Wave Born Approximation
                      (DWBA). In conclusion, our modified drop-casting method is a
                      simple, inexpensive method, which provides highly ordered
                      self-assembled monolayers of silica particles, if combined
                      with a compatible additive and a heat treatment step. This
                      method might be more general and also applicable to
                      different particles after finding an appropriate additive.},
