Electrically controlled superconductor-to-failed insulator transition and giant anomalous Hall effect in kagome metal CsV3Sb5 nanoflakes

Abstract

Kagome metals continue to attract interest due to the coexistence of electronic correlations and band topology. Here the authors use proton gating to modulate disorder and carrier density in CsV3Sb5 nanoflakes, and show its effect on superconductivity, charge density wave and anomalous Hall effect.
