Doping graphene with metal contacts
G. Giovannetti, P. A. Khomyakov, G. Brocks +3
Making devices with graphene necessarily involves making contacts with metals. We use density functional theory to study how graphene is doped by adsorption on metal substrates and…

Graphite and graphene as perfect spin filters
V. M. Karpan, G. Giovannetti, P. A. Khomyakov +6
Based upon the observations (i) that their in-plane lattice constants match almost perfectly and (ii) that their electronic structures overlap in reciprocal space for one spin dire…
