August 2012To study the influence of interface structure/strain on the ionic trans¬port, multilayer systems with different number of individual layers (layer thickness: about 22 nm) were prepared by PLD. On the top, a gold capping layer was evaporated to avoid the diffusion of 18O perpendicular to the multilayer system. Then, a slope cut was performed by ion beam milling technique and the 18O-tracer diffusion experiment was performed. Thereafter, the samples were investigated with ToF-SIMS. On the right, 2-D and 3-D elemental mappings of a sample with n = 2 and n = 5 YSZ-layers are presented. In the 2-D mappings bright colours represent a high concentration of 18O. In the 3-D mapping Sc2O3 is green, YSZ yellow and 18O red. Clearly, the 18O only penetrates (starting from the slope) into the individual YSZ-layers.
