Photoelectron diffraction of twisted bilayer graphene
S. Tricot, H. Ikeda, H. -C. Tchouekem +7
Photoelectron diffraction (PED) is a powerful spectroscopic technique that combines elemental resolution with a high sensitivity to the local atomic arrangement at crystal surfaces…
Weyl-like points from band inversions of spin-polarised surface states in NbGeSb
I. Marković, C. A. Hooley, O. J. Clark +16
Band inversions are key to stabilising a variety of novel electronic states in solids, from topological surface states in inverted bulk band gaps of topological insulators to the f…
Temperature-driven modification of surface electronic structure on bismuth, a topological border material
Y. Ohtsubo, Y. Yamashita, J. Kishi +7
Single crystalline bismuth (Bi) is known to have a peculiar electronic structure which is very close to the topological phase transition. The modification of the surface states of…
High-density two-dimensional electron system induced by oxygen vacancies in ZnO
T. C. Rödel, J. Dai, F. Fortuna +10
We realize a two-dimensional electron system (2DES) in ZnO by simply depositing pure aluminum on its surface in ultra-high vacuum, and characterize its electronic structure using a…
Co/Ni multilayers for spintronics: high spin-polarization and tunable magnetic anisotropy
S. Andrieu, T. Hauet, M. Gottwald +13
In this paper we analyze in details the electronic properties of (Co/Ni) multilayers, a model system for spintronics devices. We use magneto-optical Kerr (MOKE), spin-polarized pho…
Two-dimensional electron system at the magnetically tunable EuO/SrTiO interface
Patrick Lömker, Tobias C. Rödel, Timm Gerber +6
We create a two-dimensional electron system (2DES) at the interface between EuO, a ferromagnetic insulator, and SrTiO3, a transparent non-magnetic insulator considered the bedrock…
Two-dimensional electron systems in ATiO3 perovskites (A = Ca, Ba, Sr): control of orbital hybridization and order
Tobias C. Rödel, Manali Vivek, Franck Fortuna +6
We report the existence of a two-dimensional electron system (2DES) at the (001) surface of CaTiO3. Using angle-resolved photoemission spectroscopy, we find a hybridization between…
Engineering two-dimensional electron gases at the (001) and (101) surfaces of TiO2 anatase using light
T. C. Rödel, F. Fortuna, F. Bertran +4
We report the existence of metallic two-dimensional electron gases (2DEGs) at the (001) and (101) surfaces of bulk-insulating TiO2 anatase due to local chemical doping by oxygen va…
Direct observation of a highly spin-polarized organic spinterface at room temperature
F. Djeghloul, F. Ibrahim, M. Cantoni +23
The design of large-scale electronic circuits that are entirely spintronics-driven requires a current source that is highly spin-polarised at and beyond room temperature, cheap to…
