Image-potential states and work function of graphene
Image-potential states of graphene on various substrates have been investigated by two-photon
photoemission and scanning tunneling spectroscopy. They are used as a probe for the
graphene-substrate interaction and resulting changes in the (local) work function. The latter is
driven by the work function difference between graphene and the substrate. This results in a charge
transfer which also contributes to core-level shifts in x-ray photoemission. In this review article,
we give an overview over the theoretical models and the experimental data for image-potential states
and work function of graphene on various substrates.
