Abstract

Layered structures of DyBa2Cu3O7-x and Dy2O3 grown on (100) and (110) oriented SrTiO3 have been examined in cross section by transmission electron microscopy and energy dispersive spectroscopy to determine the feasibility of fabricating tunnel junctions with these materials. DyBa2Cu3O7-x and Dy2O3 exhibit a clear epitaxial relationship, resulting in heteroepitaxial growth of DyBa2Cu3O7-x on Dy2O3. The interfaces between DyBa2Cu3O7-x and Dy2O3 are structurally sharp, but interdiffusion between the chemical constituents occurs. Nevertheless, these results are a strong indication that high quality high-Tc superconductor tunneling junctions can be fabricated in this system.
