Hard x-ray angle-resolved photoemission from a buried high-mobility electron system
Michael Zapf, Matthias Schmitt, Judith Gabel +18
Novel two-dimensional electron systems at the interfaces and surfaces of transition-metal oxides recently have attracted much attention as they display tunable, intriguing properti…
Design and realization of topological Dirac fermions on a triangular lattice
Maximilian Bauernfeind, Jonas Erhardt, Philipp Eck +8
Large-gap quantum spin Hall insulators are promising materials for room-temperature applications based on Dirac fermions. Key to engineer the topologically non-trivial band orderin…
Tuning band alignment at a semiconductor-crystalline oxide heterojunction via electrostatic modulation of the interfacial dipole
M. Chrysler, J. Gabel, T. -L. Lee +14
We demonstrate that the interfacial dipole associated with bonding across the SrTiO3/Si heterojunction can be tuned through space charge, thereby enabling the band alignment to be…
Hard X-ray photoemission spectroscopy of LaVO/SrTiO: Band alignment and electronic reconstruction
M. Stübinger, J. Gabel, P. Scheiderer +13
The heterostructure consisting of the Mott insulator LaVO and the band insulator SrTiO is considered a promising candidate for future photovoltaic applications. Not only do…
Controlling the electronic interface properties of AlO/SrTiO heterostructures
Berengar Leikert, Judith Gabel, Matthias Schmitt +6
Depositing disordered Al on top of SrTiO is a cheap and easy way to create a two-dimensional electron system in the SrTiO surface layers. To facilitate future device applic…
