The study of a rotating method for fabricating Y1Ba2Cu3O7−x films by TFA-MOD

A water-free metal organic deposition method for YBa2Cu3O7−δthin film fabrication

“…In our study, a vial of PAn was stored for three months and remained clear without any precipitation. Using PAn and the fabrication procedure previously described in the experimental details section, YBCO film with the optimized performance could be obtained when the maximum temperature of pyrolysis (MTP) was 600 • C. Its J c was as high as 3.8 MA cm −2 (77 K, self-field, about 250 nm thick), which is comparable with those of YBCO films reportedly fabricated by the conventional all TFA solution [22] and low-fluorine solution [23]. As shown in figure 1, the pyrolysis duration was approximately 40-60 min, which was much shorter than that of the conventional TFA-MOD method [9].…”

Ethanol-based TFA–MOD method for preparation of YBCO films

“…Growth mechanism and influence of various processing parameters for TFA-MOD method have been widely investigated [8][9][10][11][12][13][14]. However, to our knowledge, little attention has been paid to the effect of solvent used for precursor solution preparation.…”

“…Methanol is the most commonly used solvent in TFA-MOD route [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. It is toxic and may cause death or blindness [15], which would involve serious health risk for industrial manufacture.…”
