Abstract: <p>We build a theoretical model for exploring the electronic properties of the two-dimensional (2D) electron gas that forms at the interface between insulating SrTiO3 (STO) and a number of perovskite materials including LaTiO3, LaAlO3, and GdTiO3. The model treats conduction electrons within a tight-binding approximation, and the dielectric polarization via a Landau-Devonshire free energy… more

Abstract: <p>Experiments have observed a two-dimensional electron gas at the interface of two insulating oxides: strontium titanate (SrTiO<sub>3</sub>) and lanthanum aluminate (LaAlO<sub>3</sub>). These interfaces exhibit metallic, superconducting, and magnetic behaviours, which are strongly affected by impurities. Motivated by experiments, we introduce a simple model in which… more
