Abstract

The presence of defects in graphene due to thin-film processing can lead to alterations of its electronic properties. Tuning of graphene's electronic properties could be achieved through control of thermal deposition of alkaline dopants (e.g. lithium) combined with low-energy deuterium ion irradiation. In this case defect generation may be controlled enhancing tunability. Using X-Ray photoelectron spectroscopy (XPS) the functionality of lithiated polycrystalline graphite and limited highly ordered polycrystalline graphite (HOPG) reveal distinct correlations between the fluency of deuterium atoms on the surface. Chemical functionalities of Li-O-D and Li-C-D are observed on the O1s and C1s XPS spectra as deuterium fluency increases. Bulk HOPG and graphite study of deuterium chemical functionality on lithiated graphite lay the foundation elucidating the synergistic effects of doping of lithium and deuterium irradiation have on graphene and hydrogenated graphene (graphane) property tunability.
