Abstract
A method of increasing grain size of polycrystalline superconducting materials for superconducting circuits, includes forming an initial superconducting epitaxial layer lattice matched to a substrate formed of a substrate material, the initial superconducting epitaxial layer formed of a compound including the substrate material and a first metal; and forming a second layer of the first metal on the initial superconducting epitaxial layer and heating the layers to increase a thickness of the initial superconducting epitaxial layer formed of the compound.
