Method of forming a single crystal material

摘要

A method of growing an epitaxial like, single crystal, superconducting film by promoting the epitaxial-like growth of film from a single nucleation site in deference to substantially all other nucleation sites on the substrate. The present invention contemplates the use of a mask to systematically expose sections of the substrate to the deposition apparatus. This mask may include an adjustable or fixed aperture and is manipulated as herein described to systematically expose areas of the substrate to the deposition apparatus.
