Silver mesostructures in particular have been in the focus of research due to the special properties of silver such as the highest electrical or thermal conductivity. Here we present the investigation of the structure, composition and time stability of thin mesoscale silver wires and dendrites, which were produced by a novel and simple electrochemical deposition approach. For the analysis Scanning Electron Microscopy, Transmission Electron Microscopy and Scanning Auger Micro Spectrometry were used. The wire diameters range down to 100 nm and the wire lengths up to 150 µm and more. The obtained structures are single-crystalline and stable under ambient conditions for several months. Thus these structures are of interest for application e.g. in micro electronics.
