Abstract

Abstract : In article number 1604447, Stuart Parkin and co‐workers demonstrate that the oxygen vacancy is a major contributor to the two‐dimensional electron gas formed at the interface between epitaxial LaFeO3 layers >3 unit cells thick and the surface of SrTiO3 single crystals. The ionic liquid gating geometry used to tune the interface conductivity by creation/removal of oxygen vacancies is shown here (Artwork: K. Roche).
