I have filed a provisional patent application for a new layered cuprate structure that may explain some of the anomalous reports of ultra-high Tc in the 123 superconductors.
I finally had the sample tested and it was not superconducting. I am focusing my efforts on fabricating a system that contains tetrahedrons instead of square planes and square pyramids. Ideally, this new material will have a 3-dimensional structure instead of containing 2-dimensional CuO2 layers. This material will be isotropic and macroscopic in nature. I already have structure-type in mind and am attempting to fabricate.
