Emergence of radial Rashba spin-orbit fields in twisted van der Waals heterostructures
Tobias Frank, Paulo E. Faria Junior, Klaus Zollner +1
Rashba spin-orbit coupling is a quintessential spin interaction appearing in virtually any electronic heterostructure. Its paradigmatic spin texture in the momentum space forms a t…
Giant asymmetric proximity-induced spin-orbit coupling in twisted graphene/SnTe heterostructure
Marko Milivojević, Martin Gmitra, Marcin Kurpas +2
We analyze the spin-orbit coupling effects in a three-degree twisted bilayer heterostructure made of graphene and an in-plane ferroelectric SnTe, with the goal of transferring the…
Tuning proximity spin-orbit coupling in graphene/NbSe heterostructures via twist angle
Thomas Naimer, Martin Gmitra, Jaroslav Fabian
We investigate the effect of the twist angle on the proximity spin-orbit coupling (SOC) in graphene/NbSe heterostructures from first principles. The low-energy Dirac bands of s…
Proximity-enabled control of spin-orbit coupling in phosphorene symmetrically and asymmetrically encapsulated by WSe monolayers
Marko Milivojević, Martin Gmitra, Marcin Kurpas +2
We analyze, using first-principles calculations and the method of invariants, the spin-orbit proximity effects in trilayer heterostructures comprising phosphorene and encapsulating…
Twist- and gate-tunable proximity spin-orbit coupling, spin relaxation anisotropy, and charge-to-spin conversion in heterostructures of graphene and transition-metal dichalcogenides
Klaus Zollner, Simão M. João, Branislav K. Nikolić +1
We present a DFT-based investigation of the twist-angle dependent proximity spin-orbit coupling (SOC) in graphene/TMDC structures. We find that for Mo-based TMDCs the proximity val…
Electric field control of spin lifetimes in Nb-SrTiO by spin-orbit fields
A. M. Kamerbeek, P. Högl, J. Fabian +1
We show electric field control of the spin accumulation at the interface of the oxide semiconductor Nb-SrTiO with Co/AlO spin injection contacts at room temperature. Th…
Spin-orbit fields in ferromagnetic metal/semiconductor junctions
M. Gmitra, A. Matos-Abiague, C. Ambrosch-Draxl +1
The methodology used to obtain the values of the spin-orbit couplings from the spin expectation values from perturbation theory was incorrect. As a result Figs. 2 and 3 are incorre…
Electron spin relaxation in graphene: the role of the substrate
C. Ertler, S. Konschuh, M. Gmitra +1
Theory of the electron spin relaxation in graphene on the SiO substrate is developed. Charged impurities and polar optical surface phonons in the substrate induce an effective…
Band-structure topologies of graphene: spin-orbit coupling effects from first principles
M. Gmitra, S. Konschuh, C. Ertler +2
The electronic band structure of graphene in the presence of spin-orbit coupling and transverse electric field is investigated from first principles using the linearized augmented…
