Аннотация:Superconducting (Tc=38 K) thin films of (Pb,Cu)2(Ba,Pb)2YCu2Oy have been grown by MetalOrganic Chemical Vapor Deposition (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. It was found that a high vapor pressure of lead-containing species in the gas phase during the film growth determines the stability of formed compounds. The results of high-resolution transmission electron microscopy (HREM) and X-ray diffraction analysis (XRD) analyses of (Pb,Cu)2(Ba,Pb)2YCu2Oy thin films are presented.
