Project
Electronic structure of modified graphene.
The project deals with the theoretical characterization of functionalized graphene. Graphene is a recently (2004) discovered material with extraordinary electronic and mechanical properties. For some applications of graphene in nanothechnology it is important to change its properties. E.g. there is a problem for using graphene as the channel material in transistors because theconductivity of graphene always remains finite, i.e. the transistor can not be switched off. This problem can be overcome by functionalizing graphene, i.e. by the chemical attachment of atoms and molecules on a graphene surface. But functionalization is also important for other applications in e.g. biotechnology and spintronics. In this project I plan to investigate this functionalization by simulating it on an atomic level with theoretical models and examining the resulting changes in the electronic and mechanicalproperties.
