Production of Y-Ba-Cu-O Nanowires and Nanotubes by Electrochemical Method

Abstract

In this work, the technological aspects of great importance YBa2Cu3O7−x superconducting materials were produced in the form of nanotube by electrochemical method. The electrochemical deposition conditions for the Y Ba Cu deposition in nanoporous Al2O3 were investigated. The heat treatment was applied to Y Ba Cu/Al2O3 nanopatterns, to form superconductive phase. The resulting nanostructures were found to be in length 4 5 μm, 177 210 nm in diameter. The produced nanostructures at −4 V and more positive potentials were Y Ba Cu nanowires, while the nanostructures deposited at the more negative potentials were of nanotube form.
