Giant Rashba splitting in graphene/SiC(0001) after Au intercalation — •Dmitry Marchenko1, A. Varykhalov1, J. Sánchez-Barriga1, M. R. Scholz1, Th. Seyller2, and O. Rader11Helmholtz-Zentrum Berlin — 2Universität Erlangen

We have recently demonstrated a giant spin-orbit splitting in graphene/Ni(111) after intercalation of a Au monolayer. The spin-orbit splitting is by 4 orders of magnitude larger than the intrinsic splitting of graphene. The intercalation approach works also for graphene on SiC(0001) which is one of the most popular substrates for high quality graphene growth. We show that in graphene/SiC the spin splitting of the Dirac-cone is zero, but intercalation of a gold layer under the graphene dramatically increases the splitting up to 120 meV.
