Latest Patents

Among his latest patents, Mukae has developed a superconducting device structure utilizing a Pr-Ba-Cu-O barrier layer. This patented technology features a superconducting transistor with a source region and a drain region formed by a YBCO film on a barrier layer composed of a PBCO film, all installed on an STO substrate. A notable aspect of this design is a gate electrode strategically placed on the thinner wall at the back of the substrate. This arrangement allows for the electric field created by the gate voltage to be effective at the interface with the barrier layer, enabling more carriers to be drawn out relative to the applied gate voltage, thus allowing a substantial superconducting current to flow.

Another of his notable patents involves a superconducting FET featuring a Pr-Ba-Cu-O channel. This technology comprises a superconducting transistor with enhanced withstand voltage, where the source and drain regions are made from oxide superconductors. These regions are complemented by a PrBa₂Cu₃O₇-x layer or an ScBa₂Cu₃O₇-x layer that acts as an intermediate region, all integrated onto a substrate. An insulation layer is placed on the intermediate region, ensuring that it functions as an insulator when the gate is off and as a superconductor when the gate is on.
