The Schottky barrier heights at the Pt/TiO₂ (001) junctions are modulated over 0.8 eV by inserting <1 nm of LaAlO₃. The large electric field in the LaAlO₃ is stabilized by preserving the continuity of in-plane lattice symmetry at the oxide interface. Lastly, these results greatly expand the application of dipole engineering to versatile polycrystalline metal/binary oxide functional interfaces.
