Abstract: A method for preparing a noble metal surface on an industrial substrate for interaction with an organic material. The method includes covering the substrate with a sequence of metal layers which may include one or more adhesion layers, one or more diffusion barriers, and ends with a noble metal layer. In an optional second step, the noble metal layer may be annealed in order to stabilize its crystal structure. Finally, the noble metal layer is subjected to one or more ion bombardment steps, which are effective to clean and precisely smooth the top surface of the noble metal layer.
