Superconducting diode using 2D oxide interface offers precise electron flow control
By
Margaret Harris
Summary
Researchers at Zhejiang University have developed a new type of superconducting diode using two-dimensional oxide interface superconductors. Unlike conventional diodes, superconducting diodes allow electrons to flow without resistance in one direction while encountering resistance in the other. First demonstrated experimentally in 2020, this new device can be precisely "edited" using atomic force microscope lithography, offering greater control over electron flow. The device has considerable potential as a platform for fundamental studies in superconductivity and could have future applications in low-power electronics and quantum computing.
