Evidence for superconducting phase coherence in the metallic/insulating regime of the LaAlO3–SrTiO3 interface electron system
A superconducting phase with an extremely low carrier density of the order of ${10}^{13}$ cm ^−2 is present at LaAlO _3 –SrTiO _3 interfaces. If depleted from charge carriers by means of a gate field, this superconducting phase undergoes a transition into a metallic/insulating state that is still ch...
