Spin relaxation in corrugated graphene
I. M. Vicent, H. Ochoa, F. Guinea
In graphene, out-of-plane (flexural) vibrations and static ripples imposed by the substrate relax the electron spin, intrinsically protected by mirror symmetry. We calculate the re…
Quantum Spin Hall Effect in Two-dimensional Crystals of Transition Metal Dichalcogenides
M. A. Cazalilla, H. Ochoa, F. Guinea
We propose to engineer time-reversal-invariant topological insulators in two-dimensional (2D) crystals of transition metal dichalcogenides (TMDCs). We note that, at low doping, sem…
Spin memory and spin-lattice relaxation in two-dimensional hexagonal crystals
H. Ochoa, F. Guinea, V. I. Fal'ko
We propose a theory of spin relaxation of electrons and holes in two-dimensional hexagonal crystals such as atomic layers of transition metal dichalcogenides (MoS2, WSe2, etc). We…
Spin-Orbit mediated spin relaxation in monolayer MoS2
H. Ochoa, R. Roldán
We study the intra-valley spin-orbit mediated spin relaxation in monolayers of MoS2 within a two bands effective Hamiltonian. The intrinsic spin splitting of the valence band as we…
Spin-orbit coupling assisted by flexural phonons in graphene
H. Ochoa, A. H. Castro Neto, V. I. Fal'ko +1
We analyze the couplings between spins and phonons in graphene. We present a complete analysis of the possible couplings between spins and flexural, out of plane, vibrations. From…
Elliot-Yafet mechanism in graphene
H. Ochoa, A. H. Castro Neto, F. Guinea
The differences between spin relaxation in graphene and in other materials are discussed. For relaxation by scattering processes, the Elliot-Yafet mechanism, the relation between t…
