ABSTRACT
Studies on the chemical modification of graphene by adding the adsorbed species on one or both faces of graphene have been carried out for a wide range of purposes. Reactions with NO and NH3, for example, have been studied for sensing applications, while studies involving the adsorbed metals have been carried out in addressing the post-silicon electronics demands. On the latter, recent studies
[1-4] have predicted the metal atoms tendency to attach onto graphene through the hexagonal C ring centers, which are commonly called the hollow sites (Fig. 5.1), with binding energies ranging from about 0.1 to 2.0 eV. It is shown that the strong changes in carbon sheet’s properties can be indeed induced by such attachments to graphene, the extent being dependent on the bonding mechanisms involved.
