Latest Patents
One of his latest patents is a method of forming a superconductor. This method involves providing a substrate and exposing it to a first atmosphere that includes precursors to form a first epitaxial layer segment. The first layer segment is then exposed to a second atmosphere, which includes precursors to form a second epitaxial layer segment. Following this, the second layer segment is exposed to a third atmosphere that includes precursors to form a third epitaxial layer segment. Each of the first and third layer segments is formed from a superconductor material, while the second layer segment is made from a different material. The collective thickness of these segments is designed to optimize the performance of the superconductor.
Another significant patent is for a composite high Tc superconductor film. This film is applied to a substrate and has a thickness of at least 5000 Angstroms, with an outer surface that maintains an average roughness not exceeding 250 Angstroms. This innovation is essential for enhancing the efficiency and effectiveness of superconducting applications.
