Latest Patents

Davis H Hartman holds a patent for "A-axis Josephson junctions with improved smoothness." This invention outlines methods to achieve low surface roughness in high-quality a-axis XBCO. The patent details several implementations, including adequate substrate preparation, calibration of flux rates for constituent atoms, and appropriate control of temperature during crystal growth. The invention also describes a wafer structure that includes a smoothing layer of c-axis XBCO, a first conducting layer of a-axis XBCO, an insulating layer, and a second conducting layer of a-axis XBCO. The patent emphasizes that for the same surface roughness, the combined thickness of the smoothing layer and the first conducting layer is greater than that of the first conducting layer without the smoothing layer. Additionally, the patent explains the process of etching a Josephson Junction from the XBCO/insulating layer/XBCO trilayer using ion mill etching techniques.
