EXTREMELY LAW RESISTANCE FILMS AND METHODS FOR MODIFYING OR CREATING SAME

摘要

The operating characteristics of a very low resistance (" ELR ") film composed of an ELR material can be improved by laminating a modifying material on the appropriate surfaces of the ELR film to produce a modified ELR film. In some embodiments of the present invention, the ELR film may be in the form of a " c-film ". Such operating characteristics include operating in an ELR state at increased temperature, carrying additional charge, operating with improved magnetic properties, operating with improved mechanical properties or other improved operating characteristics . /RTI In some embodiments of the present invention, the ELR material is a mixed-valence copper perovskite such as YBCO, but is not limited to such a YBCO. In some embodiments of the present invention, the modifying material is not limited to a conductive material such as chromium, which is readily adhered to oxygen, but such chromium.
