Graphene: Growth and functionalization

We investigate the structure and functionalization of graphene at the atomic level using scanning probe microscopy. This includes studies on epitaxial graphene grown on metals and SiC(0001). Through controlled functionalization we can manipulate the physical and chemical properties of graphene and study the interaction of molecules and metal clusters with graphene.This project is part of the SFB 953.
