- Abstract
Graphene is an intriguing object of condensed mater physics. Discovery of its fascinating transport properties renewed the interest to the studies of graphene on metallic surfaces. That leads to the technological breakthrough showing that graphene on metals can be used as a protective layer and that its synthesis on metals is the most promising way to prepare huge graphene layers. However, all technology-related and fundamental studies of the graphene-metal interfaces require the understanding of the bonding mechanism at the interface and the consequent modifications of the electronic structure of graphene compared to the free-standing case. Here we consider two representative examples of the strongly and weakly bonded graphene on metals demonstrating how surface science methods help to understand the origin of the bonding at the graphene-metal interface. These methods help to trace all modifications in the electronic structure of graphene on the microscopic and macroscopic levels.
