The Effect of a MgO Seed Layer on the Biepitaxial Growth of Y1Ba2Cu3O7-X Overlayers in Various Multilayered Thin-Films
Detailed fabrication conditions for the biepitaxial growth of six types of multilayers are reported. Each of them comprises Various layers, such as Y1Ba2Cu3O7-x, CeO2, MgO, and SrTiO3 layers, on the MgO or the SrTiO3 substrate. We found that the proper biepitaxial growth was possible for only three types of multilayers. Our experimental results reveal that the MgO seed layer plays an important role in epitaxial growth with a desired crystalline orientation, which must be due to a particular property of the MgO seed layer that is absent in the bulk MgO.
