Aspects of the electrical resistance of hydrogen loaded Pd thin films — •Stefan Wagner and Astrid Pundt — Universität Göttingen, Institut für Materialphysik, Friedrich-Hund-Platz 1, 37073 Göttingen

While the knowledge on the electrical resistance response of bulk Pd due to hydrogen loading is well established in literature, little is known on the response of Pd thin films. In the present contribution first results of systematic studies on sputtered Pd films in the thickness range from 10 to 200 nm will be presented. Hysteretic effects and hydrogen-content dependent response times of the resistance propagation have been observed, that will be discussed in terms of kinetic and structural aspects of the Pd-H system. The electrical resistance turns out to be an easily operated measure for the determination of the phase boundaries of the Pd-H system.
