Spin transport in high quality suspended graphene devices
arXiv:1207.1572 · doi:10.1021/nl301050a
Abstract
We measure spin transport in high mobility suspended graphene (μ~ 10^5 cm^2/Vs), obtaining a (spin) diffusion coefficient of 0.1 m^2/s and giving a lower bound on the spin relaxation time (τ_s ~ 150 ps) and spin relaxation length (λ_s=4.7 μm) for intrinsic graphene. We develop a theoretical model considering the different graphene regions of our devices that explains our experimental data.
