Nanostructured thin films of silver (Ag) are receiving attention in many production fields requiring adaptation to different substrate materials and fine control over surface texture, such as hi-tech industry and biomedicine. Here we report the deposition at room temperature of Ag thin films by pulsed electron ablation, the films thickness ranging from tens to hundreds of nanometers. Films micro- and nanostructure were investigated by means of AFM, STM and XRD, and chemical composition assessed by XPS. The data were elaborated and discussed in the context of depositions under non-local growth effects, and compared with pulsed electron ablation of different target materials. Our films resulted nanometrically smooth and homogeneous, with high degree of purity and characterized by a narrow distribution of grains of nanometric size at all the thicknesses considered. We suggest that a balance between the …
