δ-doped LaAlO3-SrTiO3 interface: Electrical transport and characterization of the interface potential

A. Rastogi, S. Tiwari, J. J. Pulikkotil +3

Here we investigate LaAlO_3-SrTiO_3 heterostructure withδ-doping of the interface by LaMnO_3 at less than one monolayer. This doping strongly inhibits the formation of mobile elect…
