Nanostructured noble metal films on polymer layers are of fundamental importance in the field of organic electronics. Moreover, such material combinations have gained importance for stabilizing thin polymer films. We combine sputter deposition with grazing incidence X-ray scattering (GIXS) to investigate in situ [1,2] the growth kinetics of Gold (Au) on polystyrene (PS). We therefore analyze quantitatively the Au nanoparticle layer growth such films and correlate the change in optical properties of the Au/PS system with the thickness of the gold-capped PS layer. Optical measurement methods such as UV-Vis spectroscopy or imaging ellipsometry were employed.
