Graphene on two-dimensional hexagonal BN, AlN, and GaN: Electronic, spin-orbit, and spin relaxation properties
Klaus Zollner, Aron W. Cummings, Stephan Roche +1
We investigate the electronic structure of graphene on a series of 2D hexagonal nitride insulators hXN, X = B, Al, and Ga, with DFT calculations. A symmetry-based model Hamiltonian…
Electronic and magnetic properties of -FeGe films embedded in vertical spin valve devices
Dietmar Czubak, Samuel Gaucher, Lars Oppermann +5
We studied metastable -FeGe, a novel layered tetragonal material, embedded as a spacer layer in spin valve structures with ferromagnetic FeSi and CoFeSi electrodes.…
Heterostructures of graphene and topological insulators BiSe, BiTe, and SbTe
Klaus Zollner, Jaroslav Fabian
Prototypical three-dimensional topological insulators of the BiSe family provide a beautiful example of the appearance of the surface states inside the bulk band gap caused…
Swapping Exchange and Spin-Orbit Coupling in 2D van der Waals Heterostructures
Klaus Zollner, Martin Gmitra, Jaroslav Fabian
The concept of swapping the two most important spin interactions -- exchange and spin-orbit coupling -- is proposed based on two-dimensional multilayer van der Waals heterostructur…
Quantum Anomalous Hall Effects in Graphene from Proximity-Induced Uniform and Staggered Spin-Orbit and Exchange Coupling
Petra Högl, Tobias Frank, Klaus Zollner +3
We investigate an effective model of proximity modified graphene (or symmetrylike materials) with broken time-reversal symmetry. We predict the appearance of quantum anomalous Hall…
