| fussnote | Using a molecular beam epitaxy (MBE) technique, PrGaO"3 (PGO) epitaxial films and YBa"2Cu"3O"7"-"x (YBCO)/PGO layered structures were successfully grown on SrTiO"3 (STO) (100) substrates. The reflection high-energy electron diffraction (RHEED) pattern and results of both the X-ray φ-scan and the X-ray θ-2θ scan show that the epitaxial relation of the YBCO/PGO layered structure on the STO (100) substrate was YBCO [001]PGO[110]STO[100]. The atomic force microscopy (AFM) image showed that the surface roughness value of the PGO film was less than 1 nm, and was sufficiently smooth for use as the buffer layer for YBCO on STO substrate. The surface roughness value of the PGO/YBCO/PGO structure was about 2 nm, and we found that the PGO/YBCO/PGO structure, which was deposited by using an MBE technique, has a smooth surface which can be used in layered devices. However, the T"c of the YBCO layers in PGO/YBCO/PGO structures was about 20 K lower than that in PrBa"2Cu"3O"7"-"x (PBCO)/YBCO/PBCO structures, which had the same 12 nm thick YBCO layers. Improvement of the process will be necessary in order to obtain YBCO/PGO layered structures with good superconducting properties in future studies. |
