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…
