SPP 1459: Graphene nano-flakes weakly coupled to the substrate: atomic structure, electronic states and manipulation

Graphene, the two-dimensional, single-atom thick layer of carbon is one of the materials, which are in the focus of current solid state research. The great interest is caused by the fascinating electronic and mechanical properties of graphene, which create research opportunities in fundamental and applied science and at the same time hold promise for new applications.
The interdisciplinary Priority Programme, which is comprised of scientists from physics, chemistry, materials science and electrical engineering aims at the development of fundamentals for the application of graphene in electronic devices. Different approaches for the synthesis of graphene such as epitaxial growth on silicon carbide and metal substrates, modification of organic layers and chemical synthesis of graphene nanostructures are investigated. As a prerequisite for the development of electronic devices, the specific electronic, structural, mechanical and chemical properties of graphene are studied within the Priority Programme.
Furthermore, methods for tailoring these properties by, e.g., functionalisation, are developed. Emphasis is also put on the interaction of graphene with other materials such as metals, insulators and semiconductors, which will be present in graphene devices in the form of contacts, substrates and gates.
Another important topic of the Priority Programme is the behaviour of charge carriers in graphene as well as the influence of additional factors like e.g. disorder on the carrier transport in mesoscopic and nano-scale graphene structures. Finally, graphene-based electronic devices and novel device concepts are studied. These topics are subject to experimental and theoretical investigations.
