Topographic and electronic structure of cleaved SrTiO3(001) surfaces
The topographic and electronic structure of cleaved SrTiO3(001) surfaces were studied, employing samples that either had or had not been coated with Ti on their outer surfaces prior to fracture. In both cases, SrOand TiO2-terminated terraces were present on the cleavage surface, enabling in situ studies on either termination. However, the samples coated with Ti prior to fracture were found to y...
متن کاملFirst-principles calculations of atomic and electronic structure of SrTiO3 (001) and (011) surfaces
We present and discuss the results of calculations of surface relaxation and rumpling on SrTiO3 (001) and (011) surfaces. We consider both SrO and TiO2 terminations of the (001) surface, and three terminations (Sr, TiO and O) of the polar (011) surface. The calculations are based on hybrid Hartree-Fock and density-functional theory exchange functionals, using Becke’s three-parameter method, com...
متن کاملElectronic Structure of Oxide Interfaces: A Comparative Analysis of GdTiO3/SrTiO3 and LaAlO3/SrTiO3 Interfaces
Emergent phases in the two-dimensional electron gas (2DEG) formed at the interface between two insulating oxides have attracted great attention in the past decade. We present ab-initio electronic structure calculations for the interface between a Mott insulator GdTiO3 (GTO) and a band insulator SrTiO3 (STO) and compare our results with those for the widely studied LaAlO3/SrTiO3 (LAO/STO) interf...

متن کاملInstability, intermixing and electronic structure at the epitaxial LaAlO3/SrTiO3(001) heterojunction
The question of stability against diffusional mixing at the prototypical LaAlO3/SrTiO3(001) interface is explored using a multi-faceted experimental and theoretical approach. We combine analytical methods with a range of sensitivities to elemental concentrations and spatial separations to investigate interfaces grown using on-axis pulsed laser deposition. We also employ computational modeling b...
