Molecular interactions on epitaxial graphene

Abstract

This paper reviews our recent work on molecular interactions on epitaxial graphene (EG) grown on 6H-SiC(0001). A major challenge in graphene-based devices is opening the energy band gap and doping. Molecular functionalization of graphene is one approach to modifying its electronic properties. Such surface transfer doping relies on charge separation at interfaces, and represents a valuable tool for the controlled and non-destructive doping of graphene, thereby facilitating the development of hybrid organic-graphene nanoelectronics. We have also demonstrated molecular self-assembly of bimolecular systems on EG and graphite. © 2012 The Royal Swedish Academy of Sciences.
