Superconductor to insulator transition in (111) SrTiO<sub>3</sub>/LaAlO<sub>3</sub> interface
ORAL
Abstract
We study the superconductor-to-insulator phase diagram of the (111) interface between the two band-insulators: LaAlO3 and SrTiO3. This interface has a two dimensional six-fold crystalline structure, as recently detected in the magneto-transport properties [1]. It has also been predicted to host exotic electronic orders and exhibits correlation between superconductivity and spin-orbit interaction [2]. We tune the carrier density deep into the insulating state and studied the magneto-transport properties. Our data are analyzed in the framework of superconducting fluctuations within the insulating state.
