Fabrication of YBCO films on Ag substrate by TFA-MOD method

Biaxial aligned YBCO films have been successfully deposited on Ag {110}〈110〉 textured polycrystalline substrates by metal-organic decomposition (MOD) method using Trifluoroacetate Salt (TFA). The influence of firing temperature and Ag surface defects on phase purity and texture, surface morphology of YBCO films was studied. Holding temperature at 900 ℃ for 30 mi...  (本文共4页) 阅读全文>>

Enhancing superconductivity of ultrathin YBa_2Cu_3O_(7-δ) films by capping non-superconducting oxides

In this study, we have explored the ways to fabricate and optimize high-quality ultrathin YBa_2 Cu_3 O_(7-δ)(YBCO) films grown on single-crystal(001) SrTiO_3 substrates. Nearly atomic-flat YBCO films are obtained by pulsed laser deposition.Our result shows that the termination of SrTiO_3 has only a ...  (本文共5页) 阅读全文>>

Thickness modulation effect of CeO_2 layer for YBCO films grown by pulsed laser deposition

CeO_2 film plays an essential role in nucleation and growth of YBa_2 Cu_3 O_(7-x)(YBCO) films. In this work,the dependence of superconducting properties of YBCO on CeO_2 films with different thicknesses was investigated,in order to achieve fabrication of high-performance YBCO coated conductors in industrial scale. The crystalline structure and morphology of CeO2 films with thickness ranging from 21 to 563 nm were sys...  (本文共7页) 阅读全文>>
