We consider a single layer of graphene with a Rashba spin-orbit coupling localized in the central region. Generally, a spin-orbit interaction induces a spin splitting and modifies the band structure of graphene, opening a gap between the two sublattices. We investigate the transport properties within the scattering approach and calculate the linear electric and thermoelectric conductances. We observe a weak dependence of the electric conductance with both the length of the spin-orbit region and

Our results are relevant in view of recent developments that emphasize thermoelectric effects in graphene. 2010 Mathematics Subject Classification. Primary: 82D80, 82D37; Secondary: 81U15.
