After describing the fabrication and patterning of graphene, I will present experiments, which address the phase coherence length and spin coherence length in this novel 2 dimensional electron gas. I will start with the discussion of electronic transport in graphenen ribbons patterned down to a width of ~ 20 nm. I will show that the finite size of such ribbons leads to the formation of a band-gap. Low temperature experiments show that the phase-coherence length in such samples is in the order of 1 μm. Such a long phase coherence length allows the direct observation of quantum interference phenomena in ring shaped graphene nanoribbons. I will conclude my talk with experiments addressing the spin coherence length in graphene. For these studies I have fabricated graphene based lateral spin valves. The spin injection has been achieved by means of ferromagnetic Co/Cu/Co multilayer electrodes. I will discuss the magnetoresistance of such devices in both the local and non-local geometry.
