Events in Physics
The fascinating and superlative electrical, mechanical and optical properties of graphene have been well documented over the last seven years since its isolation by Geim and Novoselov. Graphene is entirely surface, this presents one of the great challenges and opportunities for its application. Any atomic or molecular species present on the graphene surface can profoundly influence its properties. The interactions with graphene can be essentially non-invasive, such as charge transfer altering the carrier concentration, or significantly disrupt the local electronic and physical structure. The interaction between atomic and molecular species and graphene are thus of fundamental interest. The induced changes are also of technological relevance; for driving self-assembly, understanding environmental effects on graphene devices, device engineering through doping, and chemical sensing. Graphene is also an exceptional support material for inspection of nanomaterials by STM and TEM, and hence provides a platform for the study of atomic and molecular interactions on graphene. The addition of functional groups to graphene, e.g. through the use of graphene oxide or other chemically modified graphenes, adds an extra level of complexity and control. This workshop will explore the possibilities of using high-resolution microscopy and modelling to understand graphene, graphene analogues, and atomic and molecular interactions on graphene at an atomic level.
