Kurzbeschreibung (Abstract)
La0.6Sr0.4CoO3-δ (LSC) thin film electrodes on yttria stabilized zirconia (YSZ) were investigated by impedance spectroscopy, inductively coupled plasma optical emission spectrometry (ICP-OES) and time of flight secondary ion mass spectrometry (ToF-SIMS). Effects caused by different film deposition temperatures, thermal annealing and chemical etching were studied. Correlations between changes in electrode polarization resistance of oxygen reduction and surface composition were found. The surface cation composition was analyzed by ToF-SIMS and ICP-OES measurements of in situ etched LSC films allowing depth resolved compositional analysis with nominally sub nm resolution. High resolution scanning electron microscopy images illustrate changes in surface morphology.
