ResumenGraphene – a single-layer hexagonal lattice of carbon atoms displays unique electronic transport properties such as very high and tunable conductivity at room temperature together with a spin polarized transport up to room temperature. Those make graphene a promising material for applications in Spintronics. One of the key issues in the investigation of the spin polarized transport in graphene is the distinction between charge and spin signals possibly via a “non-local” technique combined with the use of magnetic contacts We investigate the adoption of focusedelectron-beam-induced deposition (FEBID) technique as an alternative route to grow resistance-matched contacts for the investigation of spin transport in graphene. We have recently discussed the influence of the FEBID process on graphene flakes. We showed that the deposition process, although up to some extent harmful for this material, is a good way of preparing complex graphene based devices. We have also reported the influence of the lithography processes (both Electron Beam and UV) on graphene. Here we aim to present a complete fabrication process and preliminary results of spin dependent transport in graphene based devices.
