Various configurations of the multi-layer of yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria (GDC) are successfully fabricated through a novel method by means of pulsed laser deposition (PLD) utilizing a split target. By controlling the deposition conditions like the laser frequency and target configuration, YSZ/GDC multi-layers of different periodicities and YSZ/GDC thickness ratios can be easily and simply realized. The multi-layer fabricated by the proposed method exhibits nearly identical physical and electrical properties to those of the multi-layer films by the conventional layer-by-layer deposition method. The present study provides a facile and effective fabrication method for the design and application of multi-layered structure.
