Non-Fluorine Based Bulk Solution Techniques to Grow Superconducting YBa2Cu3O7−δ Films

Solution-derived textured oxide thin films—a review

“…However, ferroelectrics are by no means the only thin film materials under development for electrical applications. Significant research has also been devoted during the last ten years to superconductor fabrication, especially second-generation coated conductors [5]. These conductors are based on epitaxial YBa 2 Cu 3 O 7−δ (YBCO) films deposited onto buffered biaxially textured nickel substrates.…”

Preparation of YBCO Films on CeO2‐Buffered (001) YSZ Substrates by a Non‐Fluorine MOD Method

“…[1][2][3][4] Furthermore, a recent overview of previous attempts at YBa 2 Cu 3 O 7Ϫ␦ (YBCO) film fabrication using nonfluorine-based bulk solution techniques finds that no previous report of high-J c film fabrication using fluorine-free precursors. 5 The interest in fluorine-containing precursors for YBCO films began when it was noted that such solutions decompose to carbonate-free precursor films, rather than films that contain substantial amounts of barium carbonate. 6 -9 Recently, the fabrication of YBa 2 Cu 3 O 7Ϫ␦ films through the TFA-MOD (trifluoroacetate metal organic deposition) approach 6,7 has become popular because high J c has been demonstrated on lattice-matched single crystalline substrates 7,10,11 and also on metallic substrates such as RABiTS.…”
