Abstract

Well-controlled sub-unit-cell layer-bylayer epitaxial growth of spinel alumina is achieved at room temperature on a TiO₂-terminated SrTiO₃ single-crystalline substrate. By tailoring the interface redox reaction, 2D electron gases with mobilities exceeding 3000 cm 2 V^-1 s^-1 are achieved at this novel oxide interface.
