Electronic structure, band offset, and interface electron population of the LaInO/BaSnO system
G. Hoffmann, A. A. Riaz, C. Kalha +7
Perovskite oxides and their heterostructures exhibit a wide range of functional properties. Among these materials, BaSnO/LaInO heterostructures form high-mobility two-dimen…
Switchable polarization in non-ferroelectric SrTiO
Wahib Aggoune, Matthias Scheffler
Perovskites with tunable and switchable polarization hold immense promise for unlocking novel functionalities. Using density-functional theory, we reveal that intrinsic defects can…
How ferroelectric BaTiO can tune a two-dimensional electron gas at the interface of LaInO3 and BaSnO: a first-principles study
Le Fang, Wahib Aggoune, Wei Ren +1
The emerging interest in two-dimensional electron gases (2DEGs), formed at interfaces between two insulating oxide perovskites poses crucial fundamental question in view of future…
Two-dimensional electron gas at LaInO/BaSnO interfaces controlled by a ferroelectric layer
Le Fang, Wahib Aggoune, Wei Ren +1
With the example of LaInO/BaSnO, we demonstrate how both density and distribution of a two-dimensional electron gas (2DEG) formed at the interface between these perovskit…
Fingerprints of optical absorption in the perovskite LaInO: Insight from many-body theory and experiment
Wahib Aggoune, Klaus Irmscher, Dmitrii Nabok +5
We provide a combined theoretical and experimental study of the electronic structure and the optical absorption edge of the orthorhombic perovskite LaInO. Employing density-f…
The role of the interface in controlling the epitaxial relationship between orthorhombic and cubic
Martina Zupancic, Wahib Aggoune, Toni Markurt +5
Epitaxial perovskite oxide interfaces with different symmetry of the epitaxial layers have attracted considerable attention due to the emergence of novel behaviors and phenomena. I…
