SCBD Au-Glass thin film. (a) Au clusters deposited on glass substrate with SCBD acquired with a Field Emission Scanning Electron Microscopy (FEG-SEM). (b) Schematic illustration of a percolating-tunneling system. A tunneling path is marked with a dashed line. In the inset the main phenomena which can lead to the formation of an atomic scale wire in a tunnel gap are depicted: 1. EFISD or van der Waals forces; 2. EFIE process; 3. Connected atomic wire. 4. Electromigration affecting the atomic wire: 5. Breaking of the atomic wire due to electromigration.
