Voltage-Tuned Anomalous-Metal to Metal Transition in Hybrid Josephson Junction Arrays

Author(s): S. Sasmal, M. Efthymiou-Tsironi, G. Nagda, E. Fugl, L. L. Olsen, F. Krizek, C. M. Marcus, and S. Vaitiekėnas We report on voltage-tuned phase transitions in arrays of hybrid semiconductor-superconductor islands arranged in a square lattice. A double-layer electrostatic gate geometry enables independent tuning of interisland coupling and proximity-induced superconductivity. This design enables access to the… [Phys. Rev.
