The Nb distribution was found to be uniform and unchanged across the interface, ensuring a high quality p - n junction heterointerface. We first observed the coexistence of 124 and 125 YBCO defect structure phases, appearing as planar defects in a YBCO thin film. Dispersive Y(2)O(3) nanoparticles have also been observed in the thin film. The interaction of these defect structures and Y(2)O(3) nanoparticles is thought to be beneficial for pinning flux through the entire film thickness.</p>1 aFu, Lian-feng1 aBrowning, Nigel, D.1 aRamadan, W.1 aOgale, Satishchandra, B.1 aKundaliya, D., C.1 aVenkatesan, T.  uhttps://library.ncl.res.in/content/interface-and-defect-structures-yba2cu3o7-delta-and-nb-srtio3-heterojunction
