  • Electric-double-layer transistors and ionic field-effect transistors enable continuous tuning of carrier densities in 2D superconductors, which are essential for studying novel quantum phenomena and finding new high-temperature superconductors. This Review summarizes recent advances and future development paths for electric-field-gated superconductivity in various ultrathin superconducting materials, including iron-based superconductors, transition-metal dichalcogenides, honeycomb bilayer superconductors and cuprates.
