Binary alloys and multicomponent metallic thin films containing one or more noble metals are of great interest now due to their possible applications as catalysts, sensors and photonic devices. We concentrated in our work on investigation of the binary alloy system of Au/Ag, which is considered to be very promising in the field of nonlinear optical materials [1]. In this work, we present the results of in situ Grazing Incidence Small-Angle X-ray scattering (GISAXS) and UV/Vis spectroscopy for the simultaneous radio-frequence (r.f) co-sputtering process from two metallic targets with different ratio and geometry of deposition. Post-sputtering growth characterization for the set of samples was made using Atomic Force Microscopy (AFM), GISAXS, Grazing Incidence Wide-Angle X-ray scattering (GIWAXS) and X-ray emission spectroscopy (XES). We will present comparison of the physical and structural properties depending on the ratio of the metal in bialloys and the geometry of the deposition. [1] Faupel et al., Adv. Eng.
