چکیده انگلیسی
La2Zr2O7 (LZO) epitaxial films have been deposited on LaAlO3 (LAO) (1Â 0Â 0) single-crystal surface and bi-axially textured NiW (2Â 0Â 0) alloy substrate by polymer-assisted chemical solution deposition, and afterwards studied with XRD, SEM and AFM approaches. Highly in-plane and out-of-plane oriented, dense, smooth, crack free and with a sufficient thickness (>240Â nm) LZO buffer layers have been obtained on LAO (1Â 0Â 0) single-crystal surface; The films deposited on NiW (2Â 0Â 0) alloy substrate are also found with high degree in-plane and out-of-plane texturing, good density with pin-hole-free, micro-crack-free nature and a thickness of 300Â nm. Highly epitaxial 500Â nm thick YBa2Cu3O7âx (YBCO) thin film exhibits the self-field critical current density (Jc) reached 1.3Â MA/cm2 at 77Â K .These results demonstrate the LZO epi-films obtained with current techniques have potential to be a buffer layer for REBCO coated conductors.
