Electrodeposition of YBaCuO and ErBaCuO superconductor precursor films

Electrodeposition of High Tc Superconducting Bi-Sr-Ca-CuO Nanostructures

“…As an electron passes a hole, it will push the negative charge on the reduced cation (the hole moves backwards as the electron moves forwards), generating an extra supercurrent. Some of the previously studied high-T c superconducting metal-ceramic oxides prepared through electrodeposition are Y-Ba-CuO (91K) 2 , Bi-Sr-Ca-CuO (85K-96K) 3 , Tl-Ba-Ca-CuO (102K) 4 and Er-Ba-CuO (80K) 5 . Thin films of high T c superconductors have been extensively studied and deposited by various methods which include sputtering, molecular beam epitaxy, and pulsed laser evaporation.…”

“…Thin films of high T c superconductors have been extensively studied and deposited by various methods which include sputtering, molecular beam epitaxy, and pulsed laser evaporation. 2,5 However, these techniques show a significant degradation of the superconducting properties during the fabrication process. The electrodeposition method offers an alternative and economic way of fabricating high T c superconducting thin films.…”

“…Electrodeposition has the advantage of tailoring the deposit composition which could alter the film's electronic properties. [4][5][6][7][8][9] Minimal work has been done on the electrodeposition of nanostructured superconducting materials, whereas electrodeposition of multicomponent nanowires has not yet been attempted. Piraux's group 9 reported the electrodeposition of elemental superconducting nanowires of Pb and Sn, but with no improvement in T c compared to the bulk value.…”
