High-Performance Gate-Controlled Superconducting Switches: Large Output Voltage and Reproducibility

“…The control of a superconducting current (supercurrent) via the application of a gate voltage ( V G ), currently known as gate-controlled supercurrent (GCS), has become a subject of great interest, as evidenced by the number of experimental − and theoretical studies − reported on it. Among the main motivations behind the interest in the GCS is its potential for the development of voltage-controlled superconducting logics that would intrinsically have low-energy dissipation (since based on superconductors) and better performance than other superconducting logics already available. − Compared to these, GCS-based logics would offer several advantages including higher device density (due to the smaller device size), larger number of devices connectable in series (i.e., higher fan out), stronger resilience to magnetic noise and easier interfacing with conventional metal-oxide semiconductor (CMOS) circuits to form hybrid superconducting/semiconducting computing architectures .…”
