Graphene

Caption

These images were taken with the spectroscopy method ARPES while NiSi was formed under the graphene layer. In the final image (d) scientists can identify a particular spectrum (the linear Dirac-like spectrum of grapheme electrons) indicating that the graphene interacts only weakly with the metal silicides and therefore preserves its unique properties.
