## Description

- description: The superconductor-insulator transition in two-dimensional (2D) systems
    has been extensively studied as a typical example of quantum phase transition.
    Recent investigations of highly conductive 2D systems have revealed an intervening
    metallic regime, in which the electrical resistivity saturates at the limit of
    zero temperature . The nature and origin of this metallicity remain debated, partly
    because of the lack of microscopic understanding. In this study, using scanning
    tunneling spectroscopy we investigate the metallic state and other phases observed
    in crystalline Pb monoatomic-layer superconductors formed on vicinal semiconducting
    substrates. Our spectroscopic images reveal stable and isolated vortices in the
    metallic regime, distinct from delocalized or liquidized vortices. These findings
    suggest that the saturated resistance in the metallic state arises from the pinning-free
    vortex motion driven by the finite current applied for the transport measurements.
    Our disorder-controlled microscopic experiments provide new insights into the
    fluctuation-induced phases of ultrathin crystalline two-dimensional superconductors.
