The conductivity of growing Pd-films at the percolation threshold — •Stefan Wagner, Olof Dankert, and Astrid Pundt — Institut für Materialphysik, Friedrich- Hund- Platz 1, 37073 Göttingen

The conductivity of sputtered discontinuous Pd-films at the percolation treshold will be investigated. For experimental studies an in situ 4 point measurement device is constructed to investigate the resistance under UHV conditions during sputtering. Thus, the device was implemented in an UHV sputter system. The resulting resistance curves are compared to the predictions of random resistor network theory and the underlying conduction mechanisms will be discussed.
