In situ growth of superconducting (Pb,Cu)2(Ba,Pb)2YCu2Oy epitaxial thin films by MOCVD

Superconducting (Tc=38 K) thin films of (Pb,Cu)2(Ba,Pb)2YCu2Oy have been grown by MOCVD on single crystal (001)LaAlO3 substrates in a single deposition run. The critical parameters for stabilizing lead-containing compounds in thin films are considered. A high vapor pressure of Pb-containing species...

Summary:Superconducting (Tc=38 K) thin films of (Pb,Cu)2(Ba,Pb)2YCu2Oy have been grown by MOCVD on single crystal (001)LaAlO3 substrates in a single deposition run. The critical parameters for stabilizing lead-containing compounds in thin films are considered. A high vapor pressure of Pb-containing species in the gas phase during the film growth determines the stability of formed compounds. The results of HREM and XRD analyses of (Pb,Cu)2(Ba,Pb)2YCu2Oy thin films are presented. 31 refs.
