'Charge Leakage' at LaMnO3/SrTiO3 interfaces

et al.
Direct evidence for charge leakage at the interface of epitaxial SrTiO 3/LaMnO3 superlattices with atomically sharp interfaces is provided. The direction of charge leakage can be reversed by changing the LMO/STO thickness ratio. This result will be important for the understanding of some of the reported limitations of oxide devices involving manganite/titanate interfaces. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
