Abstract:
A method of growing an epitaxial layer on a surface of a substrate, the method comprising the steps of:exposing the surface of the substrate to a gas having a velocity of at least about one meter per second to grow the epitaxial layer on the surface of the substrate, wherein during the exposing step the substrate has a temperature that is about the same as a PVD epitaxial growth threshold temperature for a chamber pressure of at most about 1Ã—10âˆ’4 torr, the gas becomes a component of the epitaxial layer, the exposing step is performed in a chamber having a pressure of at least about 1Ã—10âˆ’3 torr, and the substrate comprises a material selected from the group consisting of oxides, metals, alloys; and depositing on the epitaxial layer a layer of material selected from the group consisting of superconductor materials and precursors of superconductor materials.
