Abstract
A crystalline article includes a single-crystal ceramic fiber, tape or ribbon. The fiber, tape or ribbon has at least one crystallographic facet along its length, which is generally at least one meter long. In the case of sapphire, the facets are R-plane, M-plane, C-plane or A-plane facets. Epitaxial articles, including superconducting articles, can be formed on the fiber, tape or ribbon.
Claims3
An article, comprising:
- a single-crystal, non-planar, non-cubic, ceramic fiber having at least one crystallographic facet along its length,
- at least one epitaxial buffer layer on said fiber facet, and
- at least one epitaxial layer, comprising a REBCO-type superconductor, on said epitaxial buffer layer, wherein said fiber is sapphire or Al2O3 based, and said facet comprises an A-plane, R-plane, M-plane or a C-plane facet.
