The synthesis of copper oxycarbonate superlattices comprised of two structural types that are observed in high Tc superconductors was achieved using the pulsed laser deposition (PLD) technique. These artificially layered materials consist of specific numbers of alternately stacked infinite layer SrCuO2 and oxycarbonate Ba2−xCaxCuO2CO3 blocks, and were grown on (110) NdGaO3 using two targets. From x-ray diffraction, it was found that several unit cells of SrCuO2 could be inserted between the layers of Ba2−xCaxCuO2CO3. These results demonstrate that a large series of new structures combining oxycarbonate with oxide components can be obtained using a multitarget PLD system.
