Investigation of Electric Field-Induced Structural Changes at Fe-Doped SrTiO₃ Anode Interfaces by Second Harmonic Generation.

This materials study used optical second harmonic generation to detect electric field-induced structural changes at Pt/Fe-doped SrTiO3 anode interfaces. Reduced crystals showed steadily increasing susceptibility with increasing negative voltage, interpreted as electrostriction-related bond distortions. Oxidized…

Toward a Quantitative Understanding of the Electric Field in Thermal Metal Oxidation and a Self-Consistent Wagner Theory.

This engineering/physical chemistry study develops an analytical model and uses computer simulations to describe the electric field in oxide films during thermal metal oxidation. It reports that the electrostatic potential drop across the bulk oxide is often limited to about kBT/e, suggesting most of a larger overall…

Model for magnetic flux patterns induced by the influence of in-plane magnetic fields on spatially inhomogeneous superconducting interfaces of LaAlO3-SrTiO3 bilayers.

This study examines how spatial inhomogeneity affects a two-dimensional noncentrosymmetric superconductor in an in-plane magnetic field, motivated by LaAlO3-SrTiO3 interfaces. The authors report that spatial variation of Rashba spin-orbit coupling can generate local magnetic flux patterns through a field-induced…
