Spin-orbit-mediated spin relaxation in ballistic graphene materials
Most of the work on understanding spin relaxation in graphene for spintronic applications relies on the assumption that spin polarization is lost due to scattering and dephasing processes. Here, we present results of a recent theoretical study of spin dynamics of supported graphene in the ballistic regime [1]. This can be relevant in high-quality devices where electron scattering no longer domi...
متن کاملTheory of spin-orbit induced spin relaxation in functionalized graphene
We perform a comparative study of the spin relaxation by spin-orbit coupling induced from adatoms (hydrogen and fluorine) in graphene. Two methods are applied, giving consistent results: a full quantum transport simulation of a graphene nanoribbon, and a T-matrix calculation using Green’s functions for a single adatom in graphene. For hydrogenated graphene the dominant spinorbit term for spin r...
متن کاملSpin-orbit-mediated spin relaxation in monolayer MoS2
We study the intravalley spin-orbit-mediated spin relaxation in monolayers of MoS2 within a two bands effective Hamiltonian. The intrinsic spin splitting of the valence band as well as a Rashba-like coupling due to the breaking of the out-of-plane inversion symmetry are considered. We show that, in the hole doped regime, the out-of-plane spin relaxation is not very efficient since the spin spli...
متن کاملAnisotropic spin relaxation in graphene.
Spin relaxation in graphene is investigated in electrical graphene spin valve devices in the nonlocal geometry. Ferromagnetic electrodes with in-plane magnetizations inject spins parallel to the graphene layer. They are subject to Hanle spin precession under a magnetic field B applied perpendicular to the graphene layer. Fields above 1.5 T force the magnetization direction of the ferromagnetic ...
متن کاملEquilibrium spin current in graphene with Rashba spin-orbit coupling
The existence of a background spin current under thermodynamic equilibrium is an interesting phenomenon in the two-dimensional electron gas with Rashba spin-orbit coupling (RSOC). Here we study the equilibrium spin current (ESC) in graphene with RSOC. For an infinite graphene with uniform RSOC, we found that the ESC is proportional to λ(2) with λ the Rashba strength and mainly comes from the en...
