  The interaction between graphene and substrates provides a viable routes to
enhance functionality of both materials. Depending on the nature of electronic
interaction at the interface, the electron band structure of graphene is
strongly influenced, allowing us to make use the intrinsic properties of
graphene or to design additional functionality in graphene. Here, we present an
angle-resolved photoemission study on the interaction between graphene and a
platinum substrate. The formation of an interface between graphene and platinum
leads to a strong deviation in the electronic structure of graphene not only
from its freestanding form but also from the behavior observed on typical
metals. The combined study on the experimental and theoretical electron band
structure unveils the unique electronic properties of graphene on a platinum
substrate, which singles out graphene/platinum as a model system investigating
graphene on a metallic substrate with strong interaction.
