Title: Mariko Hosaka: Innovator in Polycrystalline Thin Film Technology
Introduction
Mariko Hosaka is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of materials science, particularly in the development of polycrystalline thin films and oxide superconductors. With a total of 2 patents to her name, her work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Mariko Hosaka's latest patents include a method for making polycrystalline thin films and associated oxide superconductors. This method involves depositing particles emitted from a target onto a substrate base to form a film while concurrently irradiating the depositing particles with an ion beam at an angle of incidence between 50 to 60 degrees. The process maintains a film temperature of less than 300 degrees Celsius, which is effective in producing excellent alignment of crystal axes in the film when the thickness exceeds 200 nm. The target material used in this process includes yttrium-stabilized zirconia, although other materials can also be utilized. A layer of superconducting substance formed on top of the polycrystalline thin film results in a superconducting film exhibiting outstanding superconducting properties.
