Doping graphene: Molecular tuning In an article “Tuning the Electronic Structure of Graphene by an Organic Molecule” that originally appeared in J. Phys. Chem. B which Professor Feng Yuan Ping and Dr Lu Yunhao collaborated with researchers from Zhejiang University has been highlighted in the Sept issue of NPG Asia Materials. Professor Feng and colleagues in Singapore and China report that the adsorption of organic molecules onto graphene could allow the electronic properties of graphene to be controlled and tuned. Their first-principles calculations show that a charge-transfer complex is created with the electron–acceptor molecule tetracyanoethylene (TCNE), allowing the electronic properties of graphene to be tuned by adjusting the coverage of adsorbed molecules.
