Abstract

Selective epitaxial growth of DyBa2Cu3O7 using Dy1-δCuδOx templates has produced superconducting wires as small as 5 microns in width. A systematic study of the effects of template composition on the superconducting properties of the wires is presented. The lateral diffusion of Dy and Cu from the template into the wires is measured with characteristic X-ray maps. Optimized Dy1-δCuδOx templates are found to be useful in defining device-size features without degradation of the superconducting properties of the film.
