Termination Control of the Interface Dipole in La${}_{0.7}$Sr${}_{0.3}$MnO${}_3$/Nb:SrTiO${}_3$ (001) Schottky Junctions

Abstract

In order to investigate the interface termination dependence of perovskite band alignments, we have studied the Schottky barrier height at La${}_{0.7}$Sr${}_{0.3}$MnO${}_3$/Nb:SrTiO${}_3$ (001) heterointerfaces. As the Nb:SrTiO${}_3$ semiconductor was varied from TiO${}_2$ termination to SrO termination by variable insertion of a SrMnO${}_3$ layer, a large systematic increase in the Schottky barrier height was observed. This can be ascribed to the evolution of the interface dipole induced to screen the polar discontinuity at the interface, which gives a large internal degree of freedom for tuning band diagrams in oxides.
