Doping graphene with metal contacts. [PDF]
Physical Review Letters, 2008 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 find that weak bonding on Al, Ag, Cu, Au, and Pt, while preserving its ...
