Abstract
Electrolyte gating with ionic liquids is a powerful tool for inducing conducting phases in correlated insulators. An archetypal correlated material is VOwhich is insulating only at temperatures below a characteristic phase transition temperature. We show that electrolyte gating of epitaxial thin films of VOsuppresses the metal-to-insulator transition and stabilizes the metallic phase to temperatures below 5 K even after the ionic liquid is completely removed. We provide compelling evidence that, rather than electrostatically induced carriers, electrolyte gating of VOleads to the electric field induced creation of oxygen vacancies, and the consequent migration of oxygen from the oxide film into the ionic liquid.
