Abstract

Heterostructures and superlattices consisting of a prototype Mott insulator, GdTiO₃, and the band insulator SrTiO₃, are grown by molecular beam epitaxy and show intrinsic electronic reconstruction, approximately ½ electron per surface unit cell at each GdTiO₃/SrTiO₃ interface. Insights into charge distribution, the influence of the electrostatic boundary conditions, and strong correlation effects will be presented.
