Abstract
A conducting 2D electron gas (2DEG) is formed at the interface between epitaxial LaFeO<sub>3</sub> layers >3 unit cells thick and the surface of SrTiO<sub>3</sub> single crystals. The 2DEG is exquisitely sensitive to cation intermixing and oxygen nonstoichiometry. It is shown that the latter thus allows the controllable formation of the 2DEG via ionic liquid gating, thereby forming a nonvolatile switch.
