YBaCuO/TlBaCaCuO epitaxial thin film superconducting multilayers-a novel approach to intrinsic Josephson junction devices

Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/ (TBCCO) thin films have been deposited on top of YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) thin films. Both layers are superconducting with T/sub c/ values of 105 K and 75 K respectively and in superconducting contact. XRD scans show the TBCCO film to grow...

Zusammenfassung:Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/ (TBCCO) thin films have been deposited on top of YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) thin films. Both layers are superconducting with T/sub c/ values of 105 K and 75 K respectively and in superconducting contact. XRD scans show the TBCCO film to grow epitaxially and c-axis oriented on the YBCO ground layer. Possible applications for such multilayers are novel concepts for intrinsic Josephson arrays requiring well defined mesa structures of TBCCO.
